Fix overwriting of hash160, sha256, and sha512 mapping results

[BowTiedWoo]

This PR addresses a bug where the results of the following expressions were being unintentionally overwritten:

• (map hash160 (list 1 2 3))
• (map sha256 (list 1 2 3))
• (map sha512 (list 1 2 3))

The fix ensures that the outputs are correctly retained without overwriting.

Fixes: #590
