Variables and formulas being copied randomly _copy

[notis]

I noticed that variables and formulas are being copied randomly in the project, without any identified reason or trigger.
It seems that sometimes when I copy an element it duplicates for no reason. Sometimes it happens, sometimes it doesn’t. But I haven’t identified a pattern.
Some variables and formulas show a connection to elements in the finder, other copies show no connection at all. They were just duplicated.

Why this happen? How can fix it?

hi, when you created a component you duplicated the variable too. However, when you put the component on the page, you should unselected the “duplicate variable” for the component not duplicate them again with the _copy.
