Shares frozen. Limit order cancellation queued for 'hours'

I am on a plus account, the only option to sell was showing me basic, and it says pending until Feb 1st! So I had to choose Limit sell, once I tried to cancel afterwards it now says pending cancellation and could take hours!? So the shares are frozen.

Is this normal?

Am I having to wait now hours until I can access and sell my shares when the price may have changed dramatically?

Please tell me this won’t happen?
