It looks like you encountered a visual bug, That "5 point" is a warning only. You will still be able to progress with Vanny without any problems.
Did you use saves from 0.3? Because this bug only happened if you use an old save
i'm playing in the newest version, when i saw the warning i checked Vannyr in the girl gallery(dont know what to call it) and saw 2 affection, unless thats the visual bug i think i just managed to mess it all up lol, though i havent gone beyond the warning since i got it just kept trying to raise her affection, btw is a walkthrough available or in the plans? Would be an appreciated addition and thx for replying in the first place👍
