[Martin Wimpress  (flexiondotorg)]

This was fixed in mate-tweak (18.04.6-1)

[Martin Wimpress  (flexiondotorg)]

Oh, I see this was encountered using 18.04.14.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Martin Wimpress  (flexiondotorg)]

Ubuntu MATE 18.04 and MATE Tweak 18.04 are both EOL and no longer supported.
