Problem with retrieving BOOL in mobile

Hi,

I have problem with retrieving Bool data in mobile game.

In desktop game works, but in mobile game not works.
Maybe is there any settings?

BP to Set:

I want to get
image

Result = empty .
In my case must be TRUE

I have tried to make one another test where is “CheckLetterFound” event with Print String if works , and yes works here is not problem with this. Only problem is with Set Bool to save/retrieving in/from memory in mobile (on desktop works)

What can be problem?
