Can you please describe this issue further

Whenever a user performs an exchange operation to receive a token that she does not previously have, the RAM for the new record will be paid by evolutiondex. The table belongs to the token contract. This is how the standard eosio.token works (the user will pay for the RAM the first time she sends some amount of that token). It is preferrable to avoid this by making the user sign an "open" action from the token contract in these cases, in the same transaction.
