[Help] "This shipment is unavailable"

Hello, is anyone able to help me fix a problem that isn’t as easy to solve as it seems? lol.
Here’s a section of my shipments code. Everything else in my shipments file is in the same exact format.


AddCustomShipment("Colt 1911", "models/weapons/s_dmgf_co1911.mdl", "m9k_colt1911", 3000, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("Colt 1911", "models/weapons/s_dmgf_co1911.mdl", "m9k_colt1911", 300, 1, true, 300, true, {TEAM_GUN})
AddCustomShipment("HK 45C", "models/weapons/w_hk45c.mdl", "m9k_hk45", 7000, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("HK 45C", "models/weapons/w_hk45c.mdl", "m9k_hk45", 700, 1, true, 700, true, {TEAM_GUN})
AddCustomShipment("Baretta", "models/weapons/w_beretta_m92.mdl", "m9k_m92beretta", 6000, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("Baretta", "models/weapons/w_beretta_m92.mdl", "m9k_m92beretta", 600, 1, true, 600, true, {TEAM_GUN})
AddCustomShipment("HK45C", "models/weapons/w_hk45c.mdl", "m9k_hk45", 5000, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("HK45C", "models/weapons/w_hk45c.mdl", "m9k_hk45", 500, 1, true, 500, true, {TEAM_GUN})
AddCustomShipment("Sig Sauer", "models/weapons/w_sig_229r.mdl", "m9k_sig_p229r", 6000, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("Sig Sauer", "models/weapons/w_sig_229r.mdl", "m9k_sig_p229r", 600, 1, true, 600, true, {TEAM_GUN})
AddCustomShipment("Raging Bull Scoped", "models/weapons/w_raging_bull_scoped.mdl", "m9k_scoped_taurus", 5000, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("Raging Bull Scoped", "models/weapons/w_raging_bull_scoped.mdl", "m9k_scoped_taurus", 500, 1, true, 500, true, {TEAM_GUN})
AddCustomShipment("TEC 9", "models/weapons/w_intratec_tec9.mdl", "m9k_tec9", 12000, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("TEC 9", "models/weapons/w_intratec_tec9.mdl", "m9k_tec9", 1200, 1, true, 1200, true, {TEAM_GUN})
AddCustomShipment("Magpul PDR", "models/weapons/w_magpul_pdr.mdl", "m9k_magpulpdr", 8600, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("Magpul PDR", "models/weapons/w_magpul_pdr.mdl", "m9k_magpulpdr", 860, 1, true, 860, true, {TEAM_GUN})
AddCustomShipment("KAC PDW", "models/weapons/w_kac_pdw.mdl", "m9k_kac_pdw", 9500, 10, false, 0, false, {TEAM_GUN})
AddCustomShipment("KAC PDW", "models/weapons/w_kac_pdw.mdl", "m9k_kac_pdw", 950, 1, true, 950, true, {TEAM_GUN})

The problem is, everytime I attempt to purchase a shipment as TEAM_GUN, it says “This shipment is unavailable.”

Thank you for your time.
