One drive album pics missing

I have Windows 10 and OneDrive came with it. I don't have a cloud subscription so everything is stored locally. I download my phone pics for my business into OneDrive and then create albums to separate them. Yesterday, I opened OneDrive and with some of the albums, the pictures were missing. The pictures are still there in the Collection and not all the albums have missing pictures. For some reason, the connection between the Collection and the grouping of the albums has been severed and I can't figure out how to reconnect or what happened. Other than going through each and every album and re-adding all the pics which would take a lot of time, I don't know what to do? Any help would be appreciated. I am posting a screenshot. You can see that I have given the Albums names and two of the albums here don't have pictures. They used to have pictures in them.
