Bedrock not replaced by Deepslate when update to 1.18.2 for worlds updated from 1.17 to 1.18 prior to fix of MCPE-149251.

I have a Realms world that the bedrock was not replaced on at all in already generated chunks. I have a copy of this world as creative (for building/designing purposes) that is not on Realms and the bedrock was replaced after the 1.18.2 hotfix. The hotfix has not fixed the Realms world, or any download of the Realms to create a new copy either.
