Problem: When adding a daemon prince with wings to an emperors children list it gives an error saying too many slaanesh choices

Expected: Should be able to allocate daemon prince to slaanesh

You have added an Allied Daemon Prince of Chaos, from the Daemons Faction.

If this was intended, then you need to add a Battleline Slaanesh unit, as per the rules for bringing Daemons in a non-Legiones Damonica list.

If you actually get intended to add a Heretic Astartes Daemon Prince (which would not trigger this validation error) add that unit instead.
