Local Map Pack Ranking

I was wondering if anyone has seen any correlation of the two. This week my Google map pack ranking for 2 different locations dropped from 1-3 to 20 or non existent . I received an alert yesterday that My Moz Domain Authority moved up 4 points. Other than that we optimize our gmb page regularly, we have regular seo and website management. So I’m confused if this could have had something to do with it? I also have a new location and that one is doing better than my older ones. And they are all 3 brick and mortar. Just a little freaked out since we get a lot of business from those 2 locations.
