Solution 1Recommended

Test for Font-Specific or File-Specific Issues

Determine if the problem is caused by a corrupted custom font or a glitch in the specific publication file you are working on.

Formatting inconsistencies often occur when a specific font file becomes corrupted or when the Publisher document itself has underlying structural issues. Isolating the variable will help determine the right fix.

1
Test a Different Font

Highlight the affected word or text box in your publication. Navigate to the Home tab and change the font to a standard system font like Arial or Calibri to see if the random formatting changes disappear.

2
Test in a New Publication

Go to File > New to create a blank publication. Type out the same text and apply the original font. If the text behaves normally, your previous publication file may be corrupted.

Test for Font-Specific or File-Specific Issues
Reporting the Issue: If the problem continues across all fonts and files, you may need to note the exact Publisher version, font name, and steps to reproduce it for Microsoft Support.
