I have a problem when want exchange to my bot inventory:

¨This shop is full and cannot accept any extra items. Please inform the shop owner to withdraw some items.¨

Why??? I have "351/800 TF2 slots" !!! (i want add 30 random weps)

Please, fix it, I am losing trades, I guess.

Okay I will try to explain this simply:

787/800 (Your total inventory space limit, all items combined), when this limit is reached your shop is full even if the account could actually take the items.
The space for each category (For example 351/800 of TF2) shows the theoretical inventory space for the account's TF2 inventory. If your bot only contains TF2 items you can store 800.

In another word, only look at the counter shown near Shop Inventory to determine how many more items your shop could take.
