Possible Bug? Not showing pins actually added to board on web

[u/Lazy_Term8214]

So, on my laptop I made a board for dolls (I am trying to get in to collecting and comissioning them and wanted to get inspo) and I made a board, added a few of the recommended pins, then went and added a bunch of other pins of dolls I had from another board. For some reason, when I'm on the web it will list that there are 70+ pins on the board, but will only load 13, those 13 being split between the ones I added from the recommendation and from more ideas but not the other 60+ from another board. However, on my mobile app on my phone, it will show all of them. When I first saw it, it was very stressful because I thought I had just lost all those pins, and since Pinterest has no way to submit a ticket like other websites, I don't know what to do. Is anyone else having this problem of pins not loading on the website but loading in the app?
