Looks like you’re removing them. Once those buttons no longer have a parent, they become orphaned. Dereferenced widgets will be garbage collected, eventually.
If you do not want them to show up now but still exist and be available later, collapse them instead:
And restore their visibility later on.
Other than that, it’s pretty unclear what is going on and what the intent is. The white target point execution wires are not even connected - is this intentional?
