(bug?) Different race pop's

[Spinoir]

Playing as Humans ive Colonized my second planet and it seems I have 2 alien pop's on the planet that I can put to work? Is this normal or a bug?

It's probably a pre-sapient species. If you policies allow it you may be able to enslave or purge them via the planet tile interface (I've seen the options listed there but I've never used them). Or, you can try to uplift them to a regular species that is part of your empire. You can either use the planet tile interface to select the "detail" button beside the species to go to the relevant interface, or use the species tab of the "people" page from the left side main menu and find the species there.

From a previous post of mine:

Uplifting species is done to pre-sapient species (there is grey text bellow the species name in the list of species that tells you it is pre-sapient). This requires the "Epigenetic Triggers" technology and is done via the species detail screen (the one where you can also set species rights). The star system where their home planet is located must be within your empire's borders. If the planet was colonised, then the tiles that were previous blocked by the native species become regular working tiles. If the planet was not colonised then it becomes a newly colonised planet that you can fully control. In either case the species becomes a regular member of your empire.

If you want to uplift them but don't yet have the required tech researched just think of those tiles as red blocker tiles (which also can't be removed until/unless you research the required tech).

Those are pre-sentient species and uplift tech is one of the last ones avaiable, sucks!
