I noticed this symbol in the library “NC7SB3157P6X” has 2 parts one switch and the other power only and the box the units’ are interchangeable and’ enabled.
In this case I believe that this option is wrong since the parts are different.
Normally when a symbol has multiple parts and these are different the check should be disabled.
I just viewed the symbol myself, and you’re right. That’s extremely odd. What’s even stranger is that the “synchronize pins” button is also active (but there might be a connection there).
I copied this component to modify it with a more complex analog switch but with the active box if I change one part they all modified.
I also don’t understand why, for example, reference and value cannot be placed in different positions within the parts.
I don’t see the “synchronize pins” box where it is located?
