When you try to view all fill ups, and then you filter by a tag, you can only view the first page of fill ups.
When you click on the link that should take you to page 2, it gets rid of the filter, so you just go to page 2 of all fill ups. There appears to be no way to view the second or later pages when you are filtering by tag.
Go to the following link and then try clicking on page 2. I cannot find a way to get to page 2 of the list when filtered.
