Model problem

[WizardJailbreak]

Hello!
My question would be, why is it if I choose a model and if I respawn myself, it switches to a basic model? My idea is that this could be the case, and how do you turn that off?
I think it could be because of this:

Default models / arms - community maps
char g_aDefaultArms[2][128] = { "models/weapons/t_arms_phoenix.mdl", "models/weapons/ct_arms_sas.mdl" };
char g_aDefaultModels[2][6][128] = {
{
"tm_phoenix",
"tm_phoenix_variantA",
"tm_phoenix_variantA",
"tm_phoenix_variantB",
"tm_phoenix_variantC",
"tm_phoenix_variantD"
},
{
"ctm_sas",
"ctm_sas_variantA",
"ctm_sas_variantB",
"ctm_sas_variantC",
"ctm_sas_variantD",
"ctm_sas_variantE"
}
};

And my other question would be, how can I replace them?
Please help, I have been trying to solve it for days
Thank you!
