The name of the design to first occupy a slot will be the name applied to all designs applied to that slot unless game is reloaded.For meta items:
This occurs in the player inventory, hotbar, shipyard computer,The tooltip name of a meta item doesn't get cleared correctly if that slot gets replaced by another meta item. storage blockYou don't need to directly swap it, and the factories as well.
In my testing a direct swap was not necessary to reproduce, as i could place design "a" in all slots and the design "b" would be labeled as "a" for all slots where "a" occupied the slot first.just moving a new meta item around to a slot that used to have a meta item reproduces this issue too.

Similar issue but only happens when you replace an used slot with another block. If you highlight/select that block to build with it, the tooltip name refreshes and it fixes itself.
