Error with filters on dashboard

Hi,

I've Enterprise Metabase on promise with version 0.47.12. I've most important error with default values of filters on dashboard. I know that maybe it is not error but breaking changes.
Follow is screenshot from one of my dashboards (sorry for polish language version) :

In my current version , the URL to dashboard looks :

https://../dashboard/7-budownictwo?filtr_daty=thisyear

but after upgrade to latest version it looks:

https://../dashboard/7-budownictwo?nr_tematu=&nr_oip=&filtr_daty=thisyear

The problem is with "nr_tematu" attribute in URL question. I don't set it in dashboard. Is exist any workaround to fast fix the problem with URL to dashboard ? Currently, I've to set default values in the variables in all my dashboards.

Regards
Pawel

I would upgrade to 1.49.5 first to exclude any bugs.

The issue is still not clear to me do you have any replication steps of what you are doing and what is happening
