Hello and thank you all for answering my questions so quickly!

This time the gridlines that I copied using copy/monitor from the arch. model are being mysterious. Some of the gridlines (see attached) are partially blocked by the view crop, even if I remove the view crop or make it not visible. It's not the annotation crop, it's the solid line crop that's doing it and it's only some grids. But since they are blocked even without the crop, I can't really say it's the crop that's blocking them. Also, when I hover over the blocked gridline, it lights up fully and good.

Whoever solves this will get a big reward.
