Logos from before 2022 do not show in side pane using new builder?

We use a LOT of logos in our newsletters, and our Logos folder currently has over 500 images in it. However, ever since I moved to the new builder, the side pane (where you pick images while building your email) only shows images uploaded in 2022 or later (about 85 of the 500+ total). To use anything older I have to insert a blank image, then use the Replace button, search the Library, and select the logo there. For a newsletter with dozens of logos this quickly becomes extremely tedious. Is this a bug? Do I need to re-upload 400+ logos to get them back into the builder view? Hoping someone can help! Here is a screen recording showing how the side pane doesn't load all images: https://www.dropbox.com/s/zx5rakygp1lcc68/Screen%20Recording%202023-02-27%20at%2011.13.15%20AM.mov?dl=0
