This means that if symmetrical windows are placed through mirroring, which is typical, tables don’t recognize identical openings as identical and create a separate opening citation for each identical opening. To be properly ‘tabled’ some of the windows must be mirror-copied along their own axes. Identifying which ones is tricky. This is the only way I was able to get the table to only cite each window opening size once.
In a what may be a related issue, I am getting persistent inverted text in a tag object.
