Image size bug on iPhone

I have a problem with an app that is occurring on an iPhone X (iOS 13.2.3) that doesn’t occur in the browser view of the app. When adding or editing a record on any table in the app, images in every table seem to resize to ‘Fill’ rather than ‘Fit’. See examples below. The images are in unrelated tables to the one I edited and as mentioned above, the problem does not occur in the browser view. Note, some of the tables I’m editing that cause the problem in other tables, don’t contain any images. Syncing does not fix the problem, only logging out and logging in again does.
