Gold Edition (Steam). Does not appear in the S&W M500 store

The S&W M500 magnum does not appear in the store, although the S&W M29 is fully upgraded. After going through the whole game and starting a new weapon, it does not appear in the store. Other types of weapons that should appear only after upgrading do not appear either. Although in the advanced settings, where you can make endless ammo, magnum and other weapons are displayed. On pirates, all weapons appear and can be bought, in the Steam version I don’t know how to solve the problem.
