Cannot sell stock symbol BXS

Alpaca Trading
#1

I am paper trading and trying to sell a stock in my portfolio with the symbol BXS and I get the following error message “asset BXS is not tradable”.

Tried liquidating the stock and I get the error “One or more positions could not be liquidated.”

I had no problems placing three other stop orders today. Why is this happening to this stock??

#2

BXS (BancorpSouth) merged with CADE (Cadence Bancorp). Stocks are now trading under the CADE symbol.

It’s in my portfolio as BXS. How do I get rid of it?

#4

Tried to sell CADE hoping it would remove BXS. No luck. I ended up with negative CADE stock.
