Testimonial section showing a blank http:// link

if you look here please:
http://www.catalyst2change.co.uk/services-clients/

i can’t work out how you enter the link you require for the testimonial section, when i used the Avia builder and add a testimonial section, when i click on the Add/Edit Testimonial option, there are only 3 fields where i can enter the text i want to appear, the top field is to enter the name of the person, the second field is to enter in the job description, and the third field is the main section where you type in quote from the person. nowhere is there a link box where you can enter in an http:// link (not that i can see) yet in the second job title field i am getting this when viewing the published pages:

Karen Delgado
Former Director Turning Point and Cambridge Education and Currently Strategic Director Enlightened HR – http://
i.e. at the end of each of the job title fields it is displaying an empty http:// link, how can i change this to the actual relevant URL links i would like displayed for each of my testimonials please?

thanks,
paul
