Tsw4 Registry Checksums Are Renewed Every Start Of Game

TSW4's registry entries for GameData and KnownContent get their checksum values renewed every time you play the game. I wonder if this is how it's supposed to be?

Example 1:
[HKEY_CURRENT_USER\Software\Dovetail Games\TSW4\KnownContent]
"TS2Prototype-WindowsNoEditor-EuropeanContentPack-coredata.pak"="9D36A625CF12D6A97F6ABE86C1F06CC278BB752D"

Example 2:
[HKEY_CURRENT_USER\Software\Dovetail Games\TSW4\KnownContent]
"TS2Prototype-WindowsNoEditor-EuropeanContentPack-coredata.pak"="A4B21DC03A891A6FBE97025841D6DE5AC64388D2"
