ZTFJ022008.6+214155.8 outburst in USNO A1.0?

   This eclipsing AM CVn object is in:

https://arxiv.org/abs/2107.07573
"Discovery and characterization of five new eclipsing AM CVn systems"

   I noticed that there is a 14 mag star in USNO A1.0.

USNO1050.00653840 022008.574 +214156.11 (2000.0) 14.0 14.4

   The position appears to be consistent with the proper motion.
Could this have been an outburst?
