Litecoin Core 0.18.1 PGP hash key not matching in checksum

I wanted to verify hash match with SHA checksum utility 2.1 before downloading the newest Litecoin core 0.18.1 client. Clearly there is an extra “c” in the hash causing it not to match. Anyone know why the SHA256 hash does not match and has an extra “c”? This has caused me some concern and kept me from downloading it.
