You can select a Listing Filter for "Regular Auctions" and see only active Auctions on the Active page. It's at top left above the tabbed columns in section labelled "Filter Listings" with drop-down list for "Listing Type".
Since you're the 2nd person to ask the question (also with long Store list that bumps to top as 30 day), I'm wondering if the feature is broken.
In truth, I've only lightly used that feature, so if it's broken I'd open a Support Case and report the problem.
