No, this is a problem with the newest version of ATBTT. More specifically it seems to be a problem with Unreal Engine 4.25, since the same problem happens if I open older versions of ATBTT (which I know did not have this problem) in UE4.25. As you have read I am working on an update that improves the action system. It is not available yet, but I will release it along with the first full version of UE4.26 UE4.26 preview 1 got released yesterday and it usually takes 1-2 months between the first preview release and the first full version release. Converting an ATBTT project to the new version will require quite a lot of manual work, as I have made many substantial changes to the toolkit.
