Source 'Advancement Speed': Does not satisfy child selection requirements

[Hendel]

I am new to Herolab online (long time Herolab Classic user) and I keep getting this error on my first Starfinder character, a ysoki mechanic.

Source 'Advancement Speed': Does not satisfy child selection requirements

Any idea what I have not yet gotten right here?

Also, it is adding a drone as a second character. Is that how it is supposed to be? I thought it might be more like the Pathfinder animal companion or familiar is in Herolab Classic as an attached minion.

Thanks!
