When discarding changes to a specific area like a mask or the focus, it discards all the edits and resets the picture without ability to restore any changes made

I use lightroom mobile on an android. When editing an image and going into more specific edits that give you an option to discard changes, such as masking, if you press the X, it gives you the option of either continuing to edit or discard changes made. In my case, if i discard te changes made to a mask, it resets my whole image, and deletes even the editing history of the image, you cannot undo the action and recover any edits made, it brings back the original image with no editing history. Same thing happened when I discarded changes made to the focus points of the image for artificial focus blur.
