Aave V2 Ethereum - reserve.totalLiquidityAsCollateral appears to be overstated in some markets

[scottnoidea]

Describe the bug
In the Aave V2 Ethereum subgraph, the reserve.totalLiquidityAsCollateral return value appears to be incorrect for some markets. It returns a value which is greater than the reserve.totalLiquidity for that market.

Incorrect markets include stETH (below), USDC and Frax. This list isn't exhaustive - there may be more.

To Reproduce
Query:

query MyQuery {
  reserve(
    id: "0xae7ab96520de3a18e5e111b5eaab095312d7fe840xb53c1a33016b2dc2ff3653530bff1848a515c8c5"
    block: {number: 16501589}
  ) {
    totalLiquidity
    totalLiquidityAsCollateral
  }
}

Response:

{
  "data": {
    "reserve": {
      "totalLiquidity": "899695114262182690563902",
      "totalLiquidityAsCollateral": "1070577614223086581220014"
    }
  }
}

Expected behavior
The totalLiquidityAsCollateral value should be less than or equal to the totalLiquidity value.
