[Video Clip Showing Issue](https://youtu.be/oaTKYWKZmRM)

I’ve linked a video showing my issue, but basically I was trying to create a new behavior tree to do an in class example, but every time I tried to set the trees blackboard information it was switching which behavior tree I was adjusting. Restarting did nothing. Is this normal behavior? Is there something I’m not getting? whats the workaround for this issue?

Nm,I figured the issue out…I think. I missed the part where you click on root and it set the blackboard its using, because it defaults to one. then, any time you select the blackboard it pulls that up where you can see the blackboards parents. ugg, still not sure why it was switching to another tree while in blackboard mode though.
