Chunks not generating in Unreal 5.5

UE_5.5 : Chunks not generating, even if I mark runtime asset label only asset label is in the chunk but not assets in the folder.

I followed the documentation to generate chunks. I added three asset labels in three folders with priority greater than 1 and differnt chunk ID’s. On packaging first not chunks were generated. After that I enabled runtime asset label like the dodumentation suggested. This time chunks were generated but only asset label is in the chunk, no assets.

Can anyone help me how to generate chunks in Unreal Engine 5.5.
