Problems whit Mount on published maps!

Hello, am trying to solve a problem related to mounting animals, specifically velocirapts. I create islands with UEFN. In the development map I have the mounting option enabled, when I test the game it works perfectly but when I publish the map it is not possible to mount them. I’ve checked the map and animal spawner device options and have the mount option enabled. Please, I would really appreciate it if you could help me with this problem, thank you very much in advance. Greetings Roi
