New Circuit with GFCI/AFCI Randomly Trips with No Load

[EEKeefe]

I moved into a house last year that has some 2-wire receptacles, and some 3-wire receptacles. I have been adding GFCIs and AFCIs where required. I recently removed the conductors and old receptacles from a circuit and replaced them with a 12 gauge two wire with ground. The first receptacle from the breaker panel is a GFCI/AFCI. I have one receptacle wired from the load side of the GFCI/AFCI receptacle, and then one wired from the 2nd receptacle. I have been noticing that the GFCI/AFCI will be tripped when I check on it. The GFCI trip light is on when it trips. I'll reset it, go to bed, and it'll be tripped the next day. There are no loads connected to this circuit. I have replaced the GFCI/AFCI and it still trips.

The other day I turned on the lights in the basement (florescent) and as soon as they turned on, the GFCI trips. It only happened once and I haven't been able to repeat it.

Summary of problem:
- Changing receptacles 2-wire to 3-wire
- Wiring and receptacles on this circuit are new
- Used existing circuit breaker
- GFCI trips on GFCI/AFCI receptacle with no loads on it
- I have replaced the GFCI/AFCI and still have the same problem
- Wiring and work was checked

Any ideas what could be the problem?
