Stuck In Blazing Retribution

I am stuck in the part where you are collecting the keys for parkour and have collected them all but am not able to put them into the correct slots in the door. Text appears above the keyholes briefly about 3 blocks from the water in the middle but right after it shows up it goes away again.

 

What fixed it for me was walking away and coming back to the door. This triggers the keyhole entities to respawn and hopefully lets you use the keys on them.

 

Thanks I tried that but I think what helped was a re log don't know why it didn't come to me sooner.
