Feed items don’t update

Hi there,

I have an issue with this plugin as the “feed items” seems stuck with old posts and don’t update anymore. In “Feed Source” settings, the “Feed Preview” on the right looks good, with latest posts but “feed items” remain outdated. The only way I found to unlock the situation was to increase the feed limit from 10 to 20. It seems it made some room for new posts. It looks like the plugin is not able to do the rotation by deleting old entries and replacing them with new ones.

I tried to “Delete and Re-import all feeds” button without success.
I’m afraid I will have the same problem when the limit of 20 will be reached. I would really appreciate some help. Thank you.
