Hi boaster_11,
It isn't possible to revert to the previous software version. If you haven't done so yet, restart your Apple Watch and the paired iPhone. Although simple, this step can help correct unexpected behavior. It's also a good idea to make sure your Apple Watch and iPhone are running the latest OS versions since this can help with overall performance: Apple security updates.
If you need more help, reach out to Apple Support directly so they can look into this with you further. They can be contacted here: Get Support, or by calling the most applicable phone number from this list: Contact Apple for support and service.
Best regards.
