GFIs Tripping for Music Stage Setup

Single Phase panel, 4 20a circuits

For this stage setup I have removed 4 GFI outlets from the stage, replaced them with standard 20a outlets. I have installed 4 GE THQL1120GFTP in the panel. The first two 20 gfi I installed tripped the gfi, the white coil wire connected to the neutral bar as in should be.

THE CONNECTIONS IN THIS PHOTO ARE FOR TROUBLESHOOTING PURPOSES ONLY


The second set of two gfi do not trip the GFI, white coil wire temp connected to the ground bar for testing

In the next photo i have discovered neutrals tied together in this j box. I assume this is what may be causing my issues.

Thank you for your help!

If the picture showing the four white wires jumped together are for more than one branch circuit than you may have found your problem if these white wires are for the branch circuits that are tripping.

I'm kind of surprised the other two GFI breakers are not tripping, but I suppose if there's nothing plugged into them they probably wouldn't even though they are wired incorrectly.

Is there anything plugged into the two circuits that are tripping? How about the two that are not tripping?

There is no load nothing is plugged in to any of the circuits. The four white wires are in the circuit connected to the 2 gfis that are tripping.

Wouldn't you want GFCI receptacles at the stage instead of GFI breakers in the panel? So they can be quickly reset when one trips...
