Price per Unit etc moved from WC Product overview to product single page

Hi there, after updating from 3.47 to 3.52 I ran into some issues…

One of the major issues is that on the page overview I had the range of price (while using grouped products) and its essential price per unit (price/100g in my case) displayed
All this information has moved to the single page overview now, where usually the different single products where nicely shown as a column beneath each other..
this overview has now been blown up with all the detailed informations that used to be behind each single product….

Any idea what went wrong/ how can I fix this?

OR – if this is something I was waiting for a long time (while using variations – NOT like now using grouped products) that each product has its price per unit…. I would need to know.. BUT this would mean that I change the whole structure of how the products are displayed in the shop…

In any case: I need to know if this is an error or something that can be change with an option…
I have attached some screenshots that show:
1) a single product (on product overview) – that looks like (ALL) the grouped product before – and which we all were used to: http://pl.vc/37o8s
2) a grouped product (on product overview page) – this has changed – why? http://pl.vc/mxws
3) a simpel products (attached to grouped product) with all the information – too much… http://pl.vc/58tu6

Please le me know…
thanks
