I have created a web map in ArcGIS Online for hydrant maintenance activities. The map uses a hydrant layer, the first layer shown below, displayed by a "Flushing Complete" field with values of "Yes", "No" or "Followup Complete". There is currently no filter applied to this layer. The subsequent layers display hydrants from the same Feature Layer but using a filter to display hydrants that need maintenance, pumping or painting. These filters are a simple "Yes" flag for the respective fields. All works well in AGOL as shown below.

When users view this map in ArcGIS Collector or Field Maps (I've only tested on Android, in my case I'm running it on a Samsung S10+), the unfiltered layer of all hydrants does not display correctly as shown below. It seems as though it is applying the filter from the "Hydrant Needs Painting" layer. Very odd behavior, has anyone seen this and if so, any insights into correcting it?

Thanks!
