Glitch? Importing character from BG1 to BG2 always randomizes HP.

Running latest version of Enhanced Edition with no mods.

Whenever I import a character from BG1 to BG2 to start a new game (whether importing character directly or importing from a save file) the characters hit points are randomized. The random HP rolls are different each time.

The only options are to accept the randomized hit points, or set the gameplay option to always max HP rolls, in which case the character will have max HP.

Not a big deal as I can just use max HP or save game editor to change HP.

Just curious if this is happening to anyone else and if there's a "fix" for it?
