[2.0.10] "Import from" planet logistics filter cannot be empty

[idontwantemail]

I searched around and asked in discord but couldn't figure out if this is a bug or intended. When in the logistics request menu for a space station, you can choose a planet to filter the request from so for instance, you can only get iron plates from vulcanis.

When you right click the filter at the bottom of this interface:

it appears to clear the planet filter, but upon editing the specific request again, the planet filter returns and is set again. So which of the two cases is correct:

1) You can not make an orbital logistic request without a planet filter, and it's a bug that you can right-click-clear the planet filter.
2) You can make orbital logistic requests that will pull from any planet, and it's a bug that clearing the filter doesn't stick.

I'm assuming it's case #1, but I thought I'd check just in case. Either way, I feel like there should be some more clarification on that tooltip with this regard.
