When editing a Report, I have added several Action items under the Quick View section.
I have the same Action available for both "For Single Record" and "For Multiple Records" and this Action has enabled the setting Execute the workflow: After confirmation. I have added confirmation messages for both Single records and Multiple records.
If I find the Action under the section "For Single Record" and I edit the action from this section, the "After confirmation" setting and the confirmation text is deleted from the Action. No matter what edit I make to the action, it overwrites the confirmation settings for multiple actions.
If I scroll further down to the "For Multiple Records" and edit the action from there, performing an identical change to the action, everything works fine.
This happens consistently across Actions in different reports.
