Hello Sweetlumps -
I am sorry to hear about the difficulties with your listings. As noted previously, the issue with the gallery images appears to be an issue on the eBay side as the data we are sending is reaching them appropriately or there would be no Header Image in your listings (which is a requirement for a listing to post). Our engineers have an open ticket with eBay regarding this issue.
As for the other issue you shared the image about - I am not aware of anything on our end that would cause this, but you may wish to try clearing the cache of your browser to see if it is an issue with the browser erroneously caching pages or try another browser to see if the issue occurs across browsers. I also suggest that you file a support case from under the Help tab of the site letting us know the details of this issue and a few sample item numbers for listings where this occurs for you so our support team can look into it.
