When attempting to place non-individual lights, only the fastener is placed and you are not able to place the stringed lights, just the fastener. There is no connection from the fastener to the player, it just places the fastener with no lights. You can do this twice in separate blocks and still no lights.

We are having this issue as well. Only the yellow lights are pulled into the inventory, even if we try to pull the colored ones. String lights are not attaching.
