Not displaying Containers in 48 - 37 & 38

I had the drop down stop functioning correctly a few weeks ago - the drop-down would just say "Empty".

I've narrowed it down to Containers - if I select "images" it shows content, but Containers and Both result in no content in the dropdown.

Using 48, and tested 37 and 38.

From my system logs these look like the specific errors:

clutter_text_get_text: assertion 'CLUTTER_IS_TEXT (self)' failed

and

Object St.Label (0x562324e96520), has been already disposed — impossible to access it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs. == Stack trace for context 0x5623197d46b0 == #0 5623198ec1d0 i file:///home/hamish/.local/share/gnome-shell/extensions/docker@stickman_0x00.com/ui/menu.js:157 (e712452eb00 @ 128) #1 (closed) 5623198ec138 i self-hosted:1429 (2921c860d150 @ 30) #2 (closed) 7ffcfde83c30 b self-hosted:804 (e71245d3a60 @ 15) #3 (closed) 5623198ec0a8 i resource:///org/gnome/shell/ui/init.js:21 (1d501c67ea60 @ 48)

Using Manjaro.

Thanks.
