Is My Non-Immigrant O-A Visa Valid After Re-Entry?

appreciate all the guidance provided by the group as i (like many) find information challenging.

During the c-19 era my 90 day expired so i will be heading to immigration to update that (tm-45) and also obtain a proof of residence letter (awaiting tm-30 from landlord) to obtain thai driver license.

my question however is:

1. i came into thailand (4 july2019) with a one year non-imm, O-A, multiple entry visa (obtained in la cal.)

2. i left country for a trip (27 dec 2019).

3. when i returned (30 dec 2019) immigration stamped me in for another year (until 28 dec 2020).

does this seem correct or is it in error and i should resolve during this next visit to immigration?
