Real Property Child Page builder

Hi. I have some very strange problems with editing pages and it took me a while to find it out. It seems there is a problem with the page builder on the website. So I just add some things I see. Because a lot of things seem wrong, I can’t describe all, but I suppose these problems will give a good view on what in general could be the problem:

1. Basicly if I open a existing page I get shortcodes instead of the page builder.
If I switch to the page builder and add a column and safe the page, I’ll end up with the normal text editor again and the column is gone.

2. If I use the DT shortcode to create the page, it seems to work. At least I can save the page and the changes will be saved as well.
Problem is that the shortcode [dt_sc_recent_properties filter=”property_type” id=”” view=”list” count=”3″/] gives me the message that no properties are available. This while we have a lot of properties in the database.
If I add this shortcode I will get a blank page saying the page isn’t working: [dt_sc_recent_properties columns=”3″ count=”90″/] If I lower the number 90 It will go good using only 10 properties. If I put 11 it goes wrong, with only 9 properties its ok.
So the filter doesn’t seem to work and I can’t add more than 10 properties.

On older pages, that I didn’t edit sinds I found out about these problems, still have 100 as “count” and working without problems.

3. If I add this shortcode: [dt_sc_recent_properties filter=”property_type” id=”” view=”list” count=”10″/]
It will say I have no properties. If I add this shortcode is shows the first 10 perfect: [dt_sc_recent_properties id=”” view=”list” count=”10″/] If I put more than 10 properties I will have the blank page again like mentioned above. I used to have 100 properties listed.

4. If you list 10 recent properties with the shortcode above, I get no pagination to view more properties. So how do I show all properties?

5. If I go to the settings of the Real Property Child I can set that Page Builder is active for various pages. If I activate this for pages I still have the normal editor when I edit a page. I can activate Page Builder in that page but when I save the page all is gone (empty page) and I have the normal editor again. If I activate the page builder again I do get the setup again I made before saving.

6. Google:
If I go to google and search site:propertyespana.com/dt_properties/magnifico-apartamento-249-m2-con-aparcamiento-en-bocairent/?lang=es the page is not known. If I do the same for the dutch translation it is known: site: site:propertyespana.com/dt_properties/schitterend-appartement-249-m2-parkeerplaatsen-bocairent/
All english and Spanish properties are unknown by google while the website is online already long time.
(I just change the permastructure to see if this will change. I had domain.com?lang=en and changed it to domain.com/en/ to see if this will change)

I have version 1.8.8 of Real property and I use 4.8 of wordpress
I have added a login for the website

Hope You can help find out the problem soon. Website is accessible but missing a lot of content.
