question about items in tzphqy bot

There are some items coloured in RED at tzphqy bot window. I know the "unknown" item are packet errors or something like that, and they don't really exist in the bot's inventory... but there are some items that i've put manually from 2moons regular client, and they appear in red. Does anybody know what does it mean ?

the bot isint perfect

i know the bot isn't perfect :D it made me suspicious because one item i use on my bot is always red, not randomly :)
