Modern Web Part - List Filters not applying

Hi All,

I've been recently experiencing an issue with my modern webpages, where list preview webparts do not show filtered views. Instead, they are showing the default "all items" list view:

(List view with filtered view, showing filter itself is correct):

I only saw one other thread describing a similar issue with a documents library view, but it had not conclusive solutions. I was wondering if anyone has any clue what this might be caused by.
