Black Market Problem/Suggestions

I'm sure this issue has already been noticed but just wanted to make it public. When I try to resell a timed gun I won from GP crates I see this:



***Note the 3,499,999 GP resale value LOL***

After clicking "OK" I receive an error:




Just a few questions:
1. Does this still mean we will still be able to resell timed guns won from GP crates after this is fixed?
2. Will timed guns won from other crates be able to be resold?
3. Will items exchanged with coupons be able to be exchanged back if the time left on the item is greater than or equal to the amount of time at the time of purchase?
4. Why is the MP7 called the MP7 7Day[C] when it's permanent?
