When converting a world made on the legacy edition of Minecraft PS4 edition, some items contained in chests don't transfer over. It appears that only items that I took from the creative inventory failed to transfer, as the locater map that came with me when I made the world is still there on Bedrock (see screenshots)
Steps to reproduce:
Create a world on the old version of Minecraft PS4 edition
Place a chest and put some items in it, optionally including the map that you spawn with
Convert the world to bedrock edition on the new version
Look in the chest on the converted world and notice the missing items
Thank you for your report!
However, this issue has already been reported in MCPE-180665, so I will be resolving this one as a duplicate.
It doesn't seem to have very much activity, but the behavior seems very consistent between the two, so while I don't have a PS4 to reproduce it myself I've marked it as community consensus. If you have any additional information you'd like to add, please head over there and leave a comment.
