Why does my behaviour tree reset its task variables

I found a few forum topics that touch on this, with few solutions, but try this! It seems like it’s been an issue with others as well, throughout the years.

It looks like you may have extra processes running for UE. Try restarting your PC, open UE, go straight to the BT, change a variable to the correct one, save, close, reopen the project and see if that works!
