Seems to be an issue on the API side. When using a page size of 30 (https://csvalpha.nl/api/v1/photo_albums?page[number]=1&page[size]=30&search=&sort=-date), the albums 351, 353 are shown after 345. However, with a page size of 10 (https://csvalpha.nl/api/v1/photo_albums?page[number]=2&page[size]=10&search=&sort=-date), they are not shown after this album.
