Help with Marquis/Mandelin results for "MDMA" Drugs

I tested two samples of what was supposed to be MDMA from completely different sources. The results were almost identical.

Sample 1 Sample 2

On both samples the Marquis test fizzled for a bit and then left the color shown. This Marquis kit is over 2 years old and has been stored in a refrigerator the entire time. After completing this test I tested some 4-AcO-MET which turned yellow instantly, as expected. Still, I'm wondering if this kit has expired.

The Mandelin turned both samples green to the blue/purple shown.

Any ideas what these could be? I've checked all the charts and can't seem to pin it down.
