The simple answer is that you can't undo it unless the edits are still active and Undo is available.
In your case I can suggest a couple of options, but one or both may be tedious depending on how many affected clips there are.
One option would be to remove all of the transitions and produce the entire timeline so that the full EQ will remain intact for each individual clip. Then you can bring the full clip onto the timeline and use the existing transitions as a guide for splitting the output video and applying the same transitions. Delete or disable all the other tracks and then produce your final copy.
A variation on that would be to remove the transitions as before but this time use the Range Select tool and then use Produce Range to create copies of each individual clip with the audio changes fully produced. Then you can replace each timeline clip with the range-produced version so the transitions will not affect the audio EQ.
The other possibility would be to find one of the autosaved project versions that were made before you made the audio edits, especially if they were among the final edits you made before producing.
You may also want to report this issue to Cyberlink
here and/or use Pack Project Materials (under the File menu) and save everything to a cloud folder on Google Drive or OneDrive so that forum members can verify that the issue occurs on their systems and maybe try out other settings or workarounds. Please see this
FAQ for more info on doing that.
