Sell price being far below other auctions

[addrianna]

Trying to sell a load of my True iron ore, Cheapest other auctions are 3g44s99c, Yet, the addon defaults too 2g28s00c with undercut set to 1c, I dont understand why.
Did I mess up something?

What does the Sell window say the historical high price is for that item? What is the normal historical price? Did you try using the Appraise All button on the Sell window? Please provide as much information for what you did to get to this point.
