Double arrow seems to stop me from recording?

Double arrow seems to stop me from recording? in the time line, there is a double arrow that I just can’t seem to remove… i am trying to do an append record and it will not allow the cursor to more in record or play?

It was working but there was a power failure earlier while I was working?

thanks

You have probably accidentally selected a very short region in the track. Click the Skip to End button, then try again.

More likely you have selected the Timeshift tool instead of the Selection tool in the Toolbar.
