Solution 1Recommended

Adjust Font Size, Zoom Level, or Change Font

Since this is primarily a font-rendering bug with Tenorite, adjusting the display scale or switching to a highly compatible alternative font immediately resolves the visual glitch.

This overflow behavior is tied to how the Excel rendering engine interprets the Tenorite font data file at very specific zoom and size combinations.

1
Change Font Size

Select the affected date cells, go to the Home tab on the ribbon, and slightly increase or decrease the font size in the Font group.

2
Adjust Zoom Level

Use the zoom slider at the bottom right corner of the Excel window to change the worksheet zoom level (e.g., from 100% to 110%) until the overflow disappears.

3
Switch to a Standard Font

If the issue persists, select the affected cells, click the Font dropdown menu on the Home tab, and choose a standard alternative font like Calibri or Arial.
