I had this problem too.

When I cleared the "log" extension at the ends of the access-list lines then the problem have been settled.

Thanks, worked for me.

I had the same issue.

Mine was caused by trying to capture an interface belonging to a port-channel.

Capturing on the port-channel instead of the physical interface resolved this.
