Sometimes when you switch SAS from orbital to surface mode , you can't directly chose the UP orientation , you need to select another one first.

(I know this is not a very big nor annoying bug but it's still one)

This one is very annoying to me.  I have to take steps to work around it all the time.  @142857 thank you for reporting it.

Here's a report I made for it quite a while ago: "Up" no longer selectable once SAS auto switches from surface to orbit velocity.  Looks like it's existed at least as far back as 0.1.2

• Side Note: I wish I got some sort of notification when my bug reports get archived.

I can shed a little more light on what's going on here.  This will always happen when SAS auto switches from surface to orbital.  That auto switch is usually triggered when your craft goes above a particular altitude.  On Kerbin this altitude is 36000m above sea level.  I know it happens on the other bodies, but I don't know the altitude for those.  I think the number is based on the size of the body or the height of it's atmosphere.

If you switch back to surface after it's switched to you to orbital, (but you still have orbital:radial out selected) it actually will have up selected, the button just won't be lit up.  It's a visual bug.  This is because surface:up maps to orbital:radial out.  When the auto switch occurs you'll notice that radial out got selected.  But for some reason, when you switch back to surface, up doesn't get highlighted.

In order to work around it, I make sure that SAS is set to hold (the padlock; as opposed to any of the specific directions like up, prograde, etc.) when I know the switch is about to happen.  So as I'm climbing through Kerbin's atmosphere, I watch for when I get to about 35000m above sea level and then press T twice.  That turns SAS off and on again.  Which causes it to default to hold.  Then when I get above 36000m I switch back to surface and select up again.

I dug into this some more today and learned that it's not limited to up/radial out.  Switching from orbital velocity to surface velocity will cause the surface target button that corresponds to the orbital target button to be selected, but not highlighted.
