Budget and needs and priorities,
the badges weren't important, so they didn't care.
A show made in the 60's jumpstarted in the 80's carried on through 2017, bound to be some differences and some minor inconsistencies. I say if the constitution class makes an appearance, give them the badges and call it a day.
Hell, if the Connie class, or rather the Big E, shows up, the uniforms and badges should look like the ones in the Kelvin movies.
