Foundry item disappeared when claiming

[pwninated]

I had built the Odonata Prime, and claimed it using the mobile app, along with several other items (which I don't think had issues).  It was a couple of days before I had a chance to try leveling up the Odonata Prime, but it didn't show as an option to equip.  I checked my inventory, and all I have is a couple of extra parts for the Odonata Prime, but not the archwings themselves.  I'm thinking the issue is with having no free archwing slots, but it didn't prompt me to buy additional slots like you normally see for weapon or warframe slots.
