2.21.0 Issues all verified!

[Carl Sorensen]

I just verified the last of the issues with Fixed_2_21_0.  Thanks everybody
for all the work!

I found a few issues that had misspelled labels, and relabeled them to the
proper spelling.

It looks like we still need to verify issues for 2.20, as well as for 2.21.1

There are also a few unverified issues from older releases, but I'll work
through those this afternoon.

Thanks,

Carl
