I can't do it from the Management portal due. I get a message that DDL is not enabled. So how else do I drop the table?
In your case, you have to KILL the underlying globals manually.
As seen in Storage definition
eg. <Global>^SVK</Global> and all others too that you didn't publish
What I've seen so far DDL enabling might not fit your expectations because of that ancient mapping.
(looks like late 80ties or before)
