How do I deal with the message: Some changes aren't reflected in source control, yet.

I'm trying to update a subflow that is in a scoped app. When I open it up in Flow Designer, I get the message:

I'm probably the only one who would work on this app, and I don't remember the last time I touched it. If I press Continue, I get a read-only version of the subflow so can't save any updates. How can I set it so I can update it again? I've tried committing in my session, but still get the message.

Is there any option for what can be done for this, I have tried with different update sets but still it is showing the same error

Workflow Studio no longer has the action box at the bottom of the flow listing, so the solution to "Add to Update Set" is no longer available. Instead filter the sys_update_xml table where Type = Flow and the Target name = Your Flow Name. Find the latest entry, this will be the last time this flow was saved. Edit this latest entry and substitute your current local update set (in the correct scope) for the entry in the update_set field. Save the record. Start a new session of Flow Designer and choose the same flow, hopefully now you can edit it.
