It looks like the Google My Business insights section, where you can see statistics on your Google Maps / Local listings, is stuck and not updating past August 5th.
Steven Erlich posted about it on Twitter yesterday and I checked and my stats are also stuck. Here is a graph showing where it stopped:
Many folks are seeing 0 clicks, impressions and any results passed August 5th but I do believe it was August 2nd the other day. So I am hopeful it is catching up and just like all those typical Search Console delays, that this is also going to catch up soon.
