Fetch Items not importing

Hello,

I have a problem updating feeds.
I thought the problem was with cron job but if I use the option Fetch items under a feed source it still doesn’t update, although the loading icon appears.

I have checked the feed source, the feed preview says there are updates. But 0 items are imported. Moreover in the updates column it says that the last updated was 2 months ago and the next update will be in 2 months. But I have set an interval of 15 minutes. I have also disabled feed to post and keyword filtering extensions.

Example feed:https://www.adventurebikerider.com/feed/
