lootcompiler Loot Compiler woes

[Jayam 5]

So I'm trying to add mod weapons onto the loot table, I've done it before with success, just this time it won't work for one reason or another, I get this error:

Unable to sort because the Icomparer.Compare<> method returns inconsistent results. 
Either a value does not compare equal to itself, or one value repeadetly compared to another value yields different results.
Icomparer: ''.

So I've tried limiting my changes to trial and error of sorts, if I remove stuff from civilian upper class, no problem, but if I remove "arifle_Katiba_F", or "30Rnd_65x39_caseless_mag", I get this damn error, now I get the same thing when I put in some certain objects too, and I can't for the life of me figure out the pattern of why it's causing this, anyone know?, I've tried adding a few items at a time, and these are giving me issues in civillian lower class:

70, arifle_mas_mp5_v
90, arifle_mas_m1014
50, arifle_mas_m4
50, arifle_mas_hk416
