Estimated liquidity pool staking asset calculated amount wrong?

**Describe the bug**

I tried staking approx 50k BTS and 400 EOS, the estimated share asset amount in return was calculated as around 37 BTWTY.BTSEOSLP

After staking, my balance of this share pool asset is closer to 49.5K BTWTY.BTSEOSLP, significantly more than the 37 quoted earlier.

**To Reproduce**

Stake BTWTY.EOS and BTS in the BTWTY.BTSEOSLP liquidity pool.

Compare estimated pool share amount to actual received pool share amount.

**Expected behavior**

The estimated pool share amount shown in the UI should be correct.

**Additional context**
Similar implementation: https://github.com/BTS-CM/astro-ui/blob/main/src/components/PoolStake.jsx#L965

Astro implementation may also be outputing an inaccurate value.

Start with the linked Astro implementation in src/components/PoolStake.jsx around line 965, then reproduce staking BTWTY.EOS and BTS in the BTWTY.BTSEOSLP pool and compare the estimated and received share amounts. Done means the UI estimate matches the actual pool-share asset amount.
