Gfci shared nuetral

[Jason H]

Anybody ever ran a 4wire for two gfi citcuits and have issues with one gfi tripping the other? It seemed to be fine when they were dedicated but having issues after adding to the gfis for load side outlets

Are you certain the load side neutrals didn’t get swapped somewhere?

Not sure I'm correctly reading your issue, but I've had that the one GFCI if tripping and load present. The rebound on sudden load drop caused an imbalance on the other and the other would trip too.

What @retire asked could also be, if your situation is the GFCI will not hold at all after the alteration.
