I've checked your forms and all upload fields aren't required so I assumed that some users do not have photo uploaded.
But if you have tested it your own and have some photo uploaded and can't see them on Google Drive then, may I ask if what are the sizes of those images? Huge file size may sometimes get delayed. As a primary solution, have you tried removing the current integration, clearing your browsers cache and reintegrate it again?
Also, you may have a lot of file in your google drive folder, please check it thouroughly. The form name is also the folder name in your Google Drive unless you have assign other name during the ntegration process.
Please let us know if you haven't sorted it out. We're here to help.
