Cannot unpack all rocket debris

I abandoned a rocket because it ran out of fuel, and 5 rocket debris fell to my home asteroid.

I could select one of them and unpack to receive some materials back, but the rest of the debris cannot be selected and they simply remain on the surface and will not disappear.

There was also a second issue where my duplicant appeared out of the nearest rocket near the escape pod instead of coming out of the escape pod directly.
