Problem removing cards from Tradelist

There a few cards on my tradelist that I no longer wanted to be there, but removing them was difficult.

Of the methods available:

1. Check the box, and Remove Selected, removes them, but then they re-appear a second later.

2. Editing the trade-list number to 0, does remove them from the page, until the page is reloaded

3. Even editing the inventory count to 0 does not remove them from the tradelist page - the cards just reappear as soon as it is reloaded.

4. Using the Edit button - this was the only way to get the changes to stick through reloads.
