After reconnecting to the server, the Promod graphics are changing. *B 5

The Promod graphics automatically change on my server. I mean, if you come to the server and fix some graphics, after a restart, they all disappear(using B 5 … screenshot uploaded). Do you have any idea why? sorry about my English.
im using this mod to my server cod4/cod4_promod_snd at master · dulkith/cod4 · GitHub
thank you soo much
