Selective Editing: my refined boundaries keep inverting/flipping along x & y axis

Hi,

I'm still learning, so I read many community discussions etc prior to posting.  On an iOS ipad I am editing a digital photo I snapped on the same device.  I have been messing around with PS Express, PS mobile app and now I've gotten looped in to Adobe Express trying to work out how to undo this issue I keep encountering.  I selected the three image areas I want to tweak or replace in selective editting.  One section was "Background" which I slightly modified from what was auto-selected.  I inadvertantly created "Object 1" and "Object 2" while trying to refine Subject etc.  No big deal, all areas look great.

I start dealing with the side issue (detailed below) and became distracted trying to find a fix (I did not find it).  I decide to return to the photo I was working on, only to find upon reopening the project that the Background, Object 1 and Object 2 are no longer how I had left them.  I assume I failed to save correctly and redo the selective editting boundaries.  Upon completion I save the project as many ways as I can figure out and take a break:  no program shut down, but when I return program has returned to homepage and I must reselect project to bring it back up.  I do so.  Again, my work has disappeared.  However, this time I notice it is still there, but it had rotated 180 degrees (or a flip on both axis).

None of the pre-set selections looked different.  Only the three I editted.  Apologies for wordiness and lack of expertise.  I want to keep learning these software, but the frequent update changes, bugs and plethora of app options that seem to do most of the same things but you have to know all of the mobile suite universe because a stand alone photo editting app for mobile is too...banal?

Side issue: what is the intended method for mobile users to use generative credits?  I was able to achieve a type of generative background replacement in Adobe Express, but there was no field to add/edit a prompt.  I could not figure out how to access that part of my plan in PS (mobile) or PS Express although I have done so easily in the past. 

Thank you in advance,
