UTM-tracking disappears after feed update

Hi!
We have just started using your plugin and it seems to be working really well for the most part, but there are a few problems that we have bumped into and that we cannot seem to resolve on our own:

1. We’ve been updating the feeds manually between 6–10 pm everyday for the past week, the plugin then reports that the next auto update will be happening the same time the next day (we have set it to update once a day), but for some reason we always find that the plugin has auto updated both our feeds at around 11 am.
2. To make matters worse: one of our auto updated feeds are supposed to have UTM-tracking, but the UTM-tracking is not there after the auto update. The settings are still there inside of the feed’s settings, but the UTM tracking is not part of the output feed anymore. Hitting the “update” button from inside the feed’s settings page always generates a new feed where the UTM-tracking is showing up as expected again.
3. We have noticed similar issues when generating the feed from the list page (Accessed by clicking the “All product Feeds” option in the WordPress side-bar menu). The feed seems to generate without issues, but the UTM-tracking is gone.

What could be causing these problems? We have enabled logging, but there doesn’t seem to be any problems reported by the plugin (although the feed generation timestamps seems to be 3 hours behind the actual events)
