Let me get this right - if one creature has See Invisible so can see someone, you think it's bad design that the Invisible Condition doesn't go away? That one person being able to see you should remove that condition for everyone?The text of the Invisible condition specifies that "You aren't affected by any effect that requires its target to be seen unless the effect's creator can somehow see you." Also, "Attack rolls against you have Disadvantage, and your attack rolls have Advantage. If a creature can somehow see you, you don't gain this benefit against that creature."
Weirdly enough, then, the Invisible condition is phrased in a way where you can lose most of the benefits of the condition (by being seen), without losing the condition itself! The only condition that does not require you to remain unseen is advantage on initiative rolls. Which makes sense. If you jump out and ambush, you want that initiative advantage given by the surprise rules.
It's poor design, but does not require absurd results. RAW you get to have the condition, but almost none of its benefits. What this means for the Invisibility spell, of course, will require clarification...
Sorry, I find that logic to be 100% wrong.
