Bulbs not being listed in [Edit] Section

[Liperty]

When adding a new action
Eg. Power Off
When I go to [Edit] the bulbs for the action - no bulbs are listed.
The LIFX application lists 4 bulbs and 3 groups.
Bulbs are on latest firmware
Lifx Application is version 3.3.3

I had previously set up an action that used two bulbs.
This action still has the bulbs listed, but when I go to [Edit] in Tasker - no bulbs are listed here either.

I have attempted re-installing the plug-in to no effect.
Please let me know if you would like further information.
