Mk14 (Classic) from Contact/Enoch doesn't have a joint rail?

[arma3marius]

Mods (complete and add to the following information):

• Arma 3: Game version: 2.00.146773
• CBA: 3.15.1

Description:
The Contact DLC/Enoch Mk14 (Classic) is missing the ability to mount mod attachments, such as scopes.

Steps to reproduce:

• Go to Arsenal or any Mission
• Compare attachments list with a mod loaded such as CUP weapons
• The Marksmen versions (Camo and Olive) work fine, but not the "Classic" version

Expected behavior:
Since all Mk14s have the same rails, all should be able to mount the same attachments. Probably an issue with joint rails.

Where did the issue occur?

• General game / weapons

Log Files:

• not applicable

Additional context:
Please refer to this link on CUP feedback: link

I have fixed it like this my config:

// load classes from CBA Joint Rails
class asdg_OpticRail1913_short;
class asdg_UnderSlot;

class cfgWeapons
{
	class DMR_06_base_F;

	class DMR_06_hunter_base_F : DMR_06_base_F {
		class WeaponSlotsInfo;
	};

	class srifle_DMR_06_hunter_F : DMR_06_hunter_base_F {
		class WeaponSlotsInfo: WeaponSlotsInfo {
			class CowsSlot : asdg_OpticRail1913_short {
				iconPosition[] = {0.52,0.36};
				iconScale = 0.15;
			};
			class UnderBarrelSlot : asdg_UnderSlot {
				iconPosition[] = {0.32,0.8};
				iconScale = 0.3;
			};
		};
	};
};
