Getting math library error while inheriting ERC4626 contract

Smart Contracts
1

Hey I'm trying to inherit ERC4626 contract "import "@openzeppelin/contracts/token/ERC20/extensions/ERC4626.sol";" and getting this math library error from the inherited contract - TypeError: Member "Floor" not found or not visible after argument-dependent lookup in type(enum Math.Rounding).
--> @openzeppelin/contracts/token/ERC20/extensions/ERC4626.sol:122:41:
|
122 | return _convertToShares(assets, Math.Rounding.Floor);
| ^^^^^^^^^^^^^^^^^^^
any solution for this?

Math.Rounding.Floor is available only from version 5.0.

You are probably using an older version, e.g., version 4.9.

If you're using Remix, maybe cleaning the cache would work.

Perhaps Remix kept OZ Contracts 4.9 cached.
