Meta inputs matching is not working in Engineering Templates

Hello there!

First of all, I would like to thank this community which is always providing support and helping with doubts. Thank you guys! it is really helpful.

I am working with engineering templates and I get some weird behavior. I have defined the meta inputs with exactly the same name as the publications of a part within the assembly to instantiate in. The issue comes when I try to instatiate selecting the meta inputs mode: It is not allowing me to select the Part with the publications to match (forbidden icon appears as the mouse pointer).


Any idea why? I used to get same issue when the name of the items (publications-metainputs) were not exactly the same, but now I dont know what is happening.

Thank you in advance! :)
