Sorry dude they did not fix themselves. Now that you state this. You need to pull the fluid from your master wipe it dry with a clean rag. Then fill it.
Then properly bleed your whole system. If you find that it does not bleed properly, then you got air in your master and you need to bench bleed it.
I am sure it is time to flush your system and this will help to do it.
You screwed up by replacing the calipers and not bleeding the system.
