GFCI Plug - Dusk to Dawn Problem

We've got an outdoor light hooked to a dusk to dawn sensor. I put a GFCI outlet between the light and the sensor so I could plug in other outdoor items that I only want to light at night.

This week I plugged in a portable sign to the GFCI outlet. The sign has GFCI on the plug. Problem is, when the circuit is off (during daylight) the GFCI on the plug trips, indicating ground was interrupted. But the GFCI on the outlet never trips.

Any ideas how to troubleshoot/rewire?

Start by plugging the sign into another outlet to see if it is the sign.

My guess is it is a tie-in problem at the GFCI. Check your line/load connections.
