In the first video I make the director appear with a Shrieker has already generated across the map. But after removing and placing the Shrieker sculk block somewhere else it stops working. No longer attracts the director and also no longer applies the darkness effect. In video 2 I try several times to make the director appear but it no longer appears.

Edit: In the java version even changing the shrieker block to another place it keeps attracting the director, why doesn't this happen in the bedrock version?
