It has come to my attention there has been a bug with spectator mode recently. I'm not sure when it was introduced but most likely during the last updates.
When you entered the /spec command ingame, you could see the target player inventory. However, when coming back from /spec, your inventory and player equipment would not be reverted.
This means you will have a duplicate of the target player's gear and inventory.
Currently, the plugin/command has been disabled completely until at least v1.16.x. There will be more extensive testing on updates in the future to make sure bugs won't be introduced.
If you lost any equipment, you can send me a PM on Discord or in-game and I'll respawn whatever is gone.
Hope to see you soon.
