EGLDUSDCF-8600f8-aa23 LP token count in Wallet not corresponding at EGLDUSDCF-8600f8-aa23 stacked on Maiar Exchange

[Dentdur]

Description of the issue:

EGLDUSDCF-8600f8-aa23 LP token count in Wallet not corresponding at EGLDUSDCF-8600f8-aa23 stacked on Maiar Exchange.

I am surprised to find that the value injected into the pool yesterday when EGLD was at $340 is lower than the current value in my possession while EGLD has risen to $390.

Total value in the pool yesterday : $6,263, today : $5,870...

Looking at my wallet balance, I see that the balance of EGLDUSDCF-8600f8-aa23 (Staked EGLDUSDCF for locked MEX) is different from the one displayed on Maiar Exchange.

- Balance via WebWallet: 792981964 (18digits)

- Balance via Maiar Exchange: 396400000 (18 digits)

The difference is 396581964 (18digits). Where did these tokens go?

On Maiar Exchange :

EGLD-USDC LP Staked:

0.0000000003964

(≈ $844.10)

Steps to Reproduce :

I don't know how to reproduce.

Actual Result (gifs and screenshots are welcome!): LP Token amount is not correct (loosed token ?)

Expected Result: The correct amount of token should be staked in Maiar Exchange

Reproduces how often: I don't know

Maiar Version (See the About Maiar page in the Settings menu): Maiar Exchange  Build c854a3a 

Reproducible on current live release (yes/no): i don't know

Additional information: OS: Mac OS | Browser: chrome |  Version: 95.0.4638

In the https://explorer.elrond.com/transactions/31c5fccd206abe18d99c29e96b6549aa721ffdaf7248a72716ffaa7e7dabcabd details i can see that i send back the 0.000000000792981964 LP Tokens to the smart contract. As i say before, Maiar Exchange do not show me the right amount of LP Token for the EGLD-USDC LMEX pool.

I think I have found where the difference comes from.

When we farm LP Token to earn LMEX, they are doubled in the SmartContract (before reward is x2)

I don't miss an LP Token, but I still don't understand why the value of my funds changed so much between 9am and 11am yesterday, while EGLD's court hasn't moved much.
