Opacity Mask does not apply unless nudged

[Silver Quill]

When I apply an opacity mask in Illustrator 2021 (version 25.1), I encounter a strange bug.

The mask does apply but its effect is not visible. To fix this, I have to get out of the opacity mask and nudge the object over. Then the masking effect becomes visible.

Though not a terrible problem, I don't like the idea of having to move things out of place and add an extra step to any process. Has this problem come up for anyone else?
