Phone backup

I have several phone with pics and a few videos on them I set up 2 of them. The main folder Mobile Photos and one phone I made a sub folder Galaxy S7, The other phone I made a sub folder Windows 10 (I also tried some other names that are not selected but on the sub folder list how do i erase them.)
Anyway it uploaded the 20 pics on the S7 buy did not put them in a sub folder also i made a new sub folder and it won’t re upload then how do i fix that?

The other phone hasn’t uploaded i believe due to only a Wi-Fi option that’s fine since it isn’t making the sub folders.
