When trying to add a related entity on another’s entity property page, the selection list at “link or create” is not capturing all possible elements. e.g. see in the gif how I try to Link to the “Review” Task Template which exists but end up in creating a second one with the same name.
Hi, Martin!
So sorry - that was caused by the bug, that is fixed already
Could you please have a try again? 
ok thanks Polina. Looks ok now!
