Specific "The Surrender" shield does not show up in Trade

I sell multiple "The Surrender" Shields but one specific Shield won't show up in trade.

Reference ID: 1,071,013,716

What I tried:
- At least 5 Minutes waiting between each Try
- Between each try I moved the Shield in to my inventory for at least 10 Seconds
- Different Sale Stash Tabs ("~price 1.1 divine" and "Sale")
- Fixed price for single Item (in both Tabs)
- Negotiate Price (in both Tabs)
- No Price set (only in "~price 1.1 divine")
- Cross checked my other selling Items (Set Trade Filter to my Account and compare the Number of Items. On sale as of writing: 33 Items, but 34 are in my Sale stash Tabs)

The Shield did not show up in Trade.

Update: Now I have two Shields I can find if Searching by my Account name, but not if searching for "The Surrender".
