Tree view is buggy in halion vst3 inside reaper

The keycommands behaviour within the tree view is very erratic. For example when renaming a layer or element, typing w or d changes the selection of the element and jumps out of the text field. There’s many other bugs like this. It’s really inconsistent and feels very buggy. I’m on reaper 7.56 on win10. halion 7.1.20.775 (64bit)
