Extreme Networks XCC pcap not opening in EyePA

I have some pcaps done with an XCC Extreme Campus Controller on an AP410C which I can open in Wireshark just fine, but not in EyePA.
Capture location on the AP (as seen in the wireless controller) is Wireless, Radio2 (5Ghz), direction BOTH. Capture is truncated at 400 bytes.
As I see, there’s no radiotap header in the pcap…
What am I doing wrong?
