ctx feed pro doesn’t update feeds according to assigned time interval

I assigned the feed to update every 5 minutes , yet it barely update once a day , and every feed update differently , some of them not updating at all

I kept looking in the plugin code , but i didn’t see anything strange
I installed crone manager and I found out that some feeds has cron tasks and other don’t , and they are scheduled to an hour at least , when I make the cron task execute now , the update doesn’t show in last update in the feed manager
