GST annual return for two registrations in different states

We are having two GST numbers, one for Karnataka and the other one for Gujarat. But pan numbers for both are same. Karnataka's GST annual turnover has exceeded 20 crore rupees and we have already filed gstr9 and gstr9c. But Gujarat's gst annual turnover is less than 20 crore rupees. should we also file gstr for Gujarat's GST number. please clarify.
