ArcGIS Pro is creating all these map controls automatically, some of them have broken sources and there is no way to delete them that I have found and they are slowly growing. Even worse, the map controls listed are not listed in the project map items.
I found them in the Data Sources panel when viewing all the maps in the catalogue of the project.
Please help. [ArcGIS Pro 2.7.1]
I'm seeing this too. There are hundreds of them. This post is the only thing I could find when searching for "MapControlMap"
And additionally, every time I click a layer in the catalog view to preview the geography there is a "transformation warning" pop-up notification (see below).
I can click back and forth between the same two layers and it will generate a new "MapControlMapXXX" each time.
Thanks for the information. My work required me to revisit this workflow yesterday and it's still an issue. I guess I'll have to submit it to Support and see what's going on here.
I'm a novice, so maybe this isn't helpful, but:
I just stumbled over these MapControlMaps, when I was packaging a project. Before packaging I klicked the mistake-analysis-button and several MapControlMaps were listed. I then klicked each MCM and repaired the mistake (missing connections or one MCM had no information (layer) attached to it). After repairing all mistakes, I was able to succesfully pack the project.
having the same issue on 2.8.3 here. it's very annoying, especially when you need to share the project as project package, it asks you to fix the broken links the mapcontrolmaps which most of them are no longer needed. not sure whether any ESRI tech team will watch this space, probably need submit a ticket (3 in a roll for this week now), more bugs in Pro....
I am having the same issue in 2.9.0: I keep getting several MapControlMap# errors but those layers are nowhere to be found in the APRX - not in the maps, sources, databases, nowhere! I've also copied the APRX (twice) to a new location to no avail. Very annoying indeed.
Problem Solved! Here is the way to fix these: If you go to "Create Project Template" then you can "Analyze" the APRX and then you can resolve the open issues (like removing the links to the layers that you had already removed!). Then you can go back to Packaging the project.
