Sea pickles not emitting light under water

Sea pickles are not emitting light when placed underwater.
Version: Bedrock 1.20 (NS Switch - in Realm)

Steps taken:

1. Created a large aquarium 
2. Placed down clay blocks at bottom
3. Placed water several blocks high (not flowing, all water is still/source block)
4. Placed Sea pickles in sets of 4 on the clay blocks and on some colored coral blocks
5. Sea pickles have the top ‘wick’ part displayed (like they did when they were collected from the ocean)

Issue: sea pickles don’t emit any light no matter where they are placed under the water in the aquarium build

Expected results: sea pickles should emit a light level when placed on a block under water.
