The target type "parent object" is not handled properly

I set the property to change the type of target to “parent object”,

but when I tried to modify the variable of the parent object, it did not change.

However, when I performed the operation on “selected object,” the variable was processed without any issues, so this appears to be a bug.

Hello! I was unable to replicate. I was able to change parent switches and variables through the child (in the video the bullet waits 2 seconds and then changes the players hp -= 1):

I wonder if your BasicSettings has a Max HP of 1. If this is the case then you cannot set HP to 2 because it will not go above the Max HP. Can you verify the Max HP allows for an HP of 2?
