Currency Exchange: Greater Jeweller's Orb : Armourer's Scrap

Currency Exchange flash repeatedly in I HAVE selection menu when select Greater Jewller's Orb (I WANT) to Armourer's Scrap (I HAVE), and barring player to actually view the currency exchange properly.

The flash explicitly happen in this exchange, other desirable orbs (I WANT) to Armourer's Scrap (I HAVE) does not exhibit flashing I HAVE menu.

Please fix.
