I am well versed with solidity and often use Remix IDE. Quite recently, despite adding a compiler version in my code. I am still getting this warning

` Warning: Source file does not specify required compiler version! Consider adding "pragma solidity ^0.6.5;".`

The code:

    pragma solidity ^0.6.5;'
    Contact A{
    <Something>
    }

Any guidance, why is this happening?
