Split tool deleting split

I’ve been using the split tool to split joints, but now there’s a trashcan symbol next to the selected split method and it instead split a Section of the object then deleted it, almost like it’s acting like a square Trim. Is this a bug or can I fix it somehow?

Trash can is just a UI hint.

Yes trim line has been updated to use regular Boolean (using rectangle under the hood) but there is a bug with the Split tool.
You can rectangle instead (you can easily scale/rotate the shape by using 2 fingers)
