Wrong route when buying my BEP20 token

[InfinitUP]

Hi,

I am the dev of a BEP20 token and I have an issue when buying it through poocoin. The main LP is IUP/BNB and someone created a pool IUP/BUSD with less than 20 BUSD in it. The price of this pool is 100x less than the price of the main LP. This results in poocoin automatically trying to use this LP to buy the token. As the LP was so small I tried to add some liquidity but it didn't solve the issue.
It seems that the IUP/BUSD pool is bugged and no one can swap using it. I tried to swap directly through router v2 smart contract but the transaction always fails.

Some swaps have been made using this pool so I don't thing the issue comes from our token.

The problem is exactly the same as this one: pancakeswap/pancake-swap-interface-v1#95
