Server core, version: Paper, 1.16.1 TradeUI version: 1.1.5b

TradeUI does not support 1.16+ versions of Minecraft I'll be adding support for 1.16 in the near future

[RyanA3]

If you want to use TradeUI for 1.16+ right now, I believe setting 'use-commands' to false in the config will disable the clickable text, which is causing the issue in 1.16, however it will also require players to shift right click each other instead of using commands.
