Is this a known bug or some special functionality? I noticed that a feature I'd hidden has both Hide and Show available.

Out of curiosity I tried hiding the hidden feature and it ended up hiding a different unrelated feature (boss extrude, separate body).

After that I no longer got the dual icons but hiding and showing no longer worked properly for either of those bodies.

Hiding the one would hide the other too. Showing the one would show the other too.

I tried restarting SW and the issue persisted.

However after trying hiding and showing some other bodies in the model, the problematic bodies have returned to normal.
