Hello @Impressive_Bee2617
I hope you are doing well, and thanks for reaching out. We’re sorry for the trouble you had.
Could you please share more details about the issue? Are you on a Mac or Windows machine, and what is the version?
Is it happening with all the PDFs, or with one specific PDF? Please ensure you have the latest version of Acrobat installed on the machine: Version: 26.001.21563. Planned update, May 18, 2026. Check for any pending updates by navigating to Menu > Help> Check for Updates. Install the updates, restart the app and the machine, and try again.
Suggestions:
Add checkmarks one at a time (don’t keep the tool “sticky”): In Acrobat, click Add Checkmark (✓) and click once where you need it. After placing a checkmark, press Esc or select the Hand/Selection tool to exit the checkmark tool before moving to the next page.
This ensures Acrobat doesn’t accidentally stamp another checkmark in the same spot on the new page. The key is to avoid leaving the checkmark tool continuously selected as you navigate pages.

If the issue still continues, please share the following details for further investigations:
- a short screen recording of the behavior,
- your OS,
- your Acrobat version (Help > About Acrobat),
- and note whether it happens in one file or every file.
Let us know how it goes, and share your observations.
Regards,
Anand Sri.
