Hi @Mike Malloy,
Thank you for posting your question in the Microsoft Q&A forum.Based on your description, the issue is highly due to Excel cell properties that may affect the text display (like Wrap text, cell styles, etc.). Display zoom level can also be the culprit of this behavior since Excel renders rows inconsistently in different zoom levels.
I suggest you can try following this guideline to narrow down the situation step by step:
1- Open Excel safe mode
- Press Win + R to open Run dialog box > type excel /safe > hit Enter.
- In Safe mode, try opening the problematic file to see if the issue still persists there.
2- Check cell formatting
- Select the rows having issue and right click > Format cells > Alignment tab
- Check if Wrap text is off, Shrink to fit is off and vertical alignment is consistent with other rows (Center suggested)

- If possible, you can try selecting the row > Home tab > Editing > Clear > Clear Formats

3- Reset zoom and display
- Set the zoom setting to different scale (80%, 120%, etc.) and reset it back to 100% to see if the issue persists.
