Unable to trade mod [Negate]

[(PSN)m3wheeling]

Yesterday I wanted to buy the mod [Negate].  I used trade chat and on 2 separate users I was unable to complete the trade.  They invited me to their dojos.  I was able to bring up my side and enter my plat but both the sellers messaged me they couldn't sell Negate.  One said they didn't understand and the other that it was odd.  They really didn't expand on what they encountered.  Last time I traded was roughly a week ago.  Any idea on why someone would not be able to sell this mod?

Negate is for a Sentinel. The game won't let a player sell the last item of a unique ability. The seller would need to have two of them in their inventories in order to sell it to someone. It's a condition for Precept Mods.

I belive the seller must own more than 1 copy of the mod to be able to trade it. Thats because its a unique ability mod.
