The POH is developed by the builder.
Some kits no doubt have a spec list or maybe a suggested one, but it's on the builder to produce it - for mine I just "borrowed" liberally from several that fit the bill. Sounds like the guy who put your aircraft together just cut-and-pasted from the E-LSA one, or possibly wasn't aware that when he went pure EAB he wasn't required to use the E-LSA one.
The Operating Limitations from the FAA is the ruling authority here. Change the POH to match them. If you want to be really super honest, put a "change page" at the front describing what was changed and why.
For example, my Operating Limitations state Daytime VFR Only. I could put all manner of stuff in the POH about nighttime flying, but that won't make it legal to fly it at night. The flip side is that if the Operating Limitations allowed for flying at night and I wrote in my POH that it isn't, one could fly the plane at night and not get into dutch....though it would have to be straightened out and the POH fixed.
Don't worry about FAR's. It's an Experimental, and this is maintenance. You're fixing the POH.
