I'm not sure of the root cause of this, but somehow a data type gets dropped from xdat_meta_element. When that happens, the extension value for experiments of that type gets set to null. Any experiments with a null value for extension then get grouped together in the query performed in the DefaultGroupsAndPermissionsCache.resetTotalCounts() method. This isn't something we want to fix in that code but it is something we should detect and then notify users about.
