There appears to be a bug in VW2024.  You cant reshape floors with the Reshape Tool without double clicking into the shape. If you happen to reshape the floor the selection handle moves but the floor does not.  There are also snapping issues, that I need to explore.  May be problems on my end.   If you do try to reshape, the floor gets corrupted and cannot be selected.  VW 2023 does not work this way.   I will submit this as a bug.     Reshape floor problem.
