Have you tried the 'resetenv' command from u-boot?

resetenv- resetenv      - earse environment sector to reset all
variables to default.

I haven't tried this on a WRT1900AC, but on the EA4500 (which has a
somewhat similar u-boot) it correctly resets everything to default
values. Given that your u-boot settings are gone one way or another (as
your fw_printenv later shows) this might be worth a try.
