Hi!
I determinate that rails didn’t recognized as weapon.
I check in API explorer - it has IsWeapon set to False (see screenshot below). Is it bug ?

Issue was with missing matching patterns for meta-modules.
public class ModuleButtonTooltip : IModuleButtonTooltip
{
static readonly string[] IsWeaponSetIndicatorLabelRegexPattern = new string[]{
//new patterns rails
“Gauss Gun”,
“Coil Gun”,
//new patterns torpedo and missile
“Torpedo Launcher”,
“Missile Bay”,
};

Thank you @Misato for this addition.
I merged this into the main development branch:
