Correct. The USTA bases your rating on your eligible gender specific matches only, eligible being only the leagues your section/district elects to use. So your mixed matches don't count and I don't know of any section that uses combo matches either.
If you don't play 3 gender specific matches from eligible leagues, but play enough mixed matches, you can get a mixed-exclusive rating, but I believe when you have a gender specific rating from the prior year, that still carries over instead and seems to be what happened with you.
