Field Change/Edit Triggering Field Default

Hi, I found that a field change is triggering a bunch of field default codes that are irrelevant to the current code. It's not called or referred in the field change or field edit in any level codes(Field, Record, Component). In the case of my field edit - it's a simple validation and in the trace, I can see that once the field edit is over, the other default codes are running.

Any input on finding the reason will be appreciated.
