Publish Attribute Mode, Attributes disappear on save

Hi, we’re trying to streamline comp, and we thought we’d worked out a method to build the presets we needed however we’ve ran into a problem.

Our preset creates custom offset shadows via the colour selector, which is then grouped, then uses Publish Attribute Mode to promote common controls to the group node. This is a massive time saving, and helps with continuity.

When we place the group from the library it’s fine. We then set it up, great. But if we save and reopen the published attribute for the colour selector disappears. The previous settings are maintain, just the attribute link between what’s in the group and the published attribute disappears.

This only happens once a colour has been selected in the colour selector. If there’s no colour then the attribute remains published.

Is this a known bug? Is it likely to be fixed?

Many thanks,
C
