Mdl cache : "item" needs to be recomplied.

Hi guys, I’m just looking for a little bit of help from somebody whom may of come across the same issue.
I’ve been trying too clean up my server console although I can not seem too find a fix for these errors:

MDLCache: props_Lighting\AirportLight01.mdl needs to be recompiled
MDLCache: props_interiors\LightSconce02.mdl needs to be recompiled
MDLCache: props_buildings\Storefront_Window_neutral.mdl needs to be recompiled
MDLCache: props_exteriors\wood_railing004c.mdl needs to be recompiled
MDLCache: Props_Lighting\LightFixture02.mdl needs to be recompiled
MDLCache: props_mall/mall_display_04.mdl needs to be recompiled
MDLCache: props_mall/mall_display_11.mdl needs to be recompiled
MDLCache: props_mall/mall_display_06c.mdl needs to be recompiled
MDLCache: Props_Lighting\corner_light_180.mdl needs to be recompiled
MDLCache: props_interiors\chairs_airport.mdl needs to be recompiled
MDLCache: Props_Plants\PlantAirport01.mdl needs to be recompiled

If anyone could shed some light for me it would extremely appreciated. (:

Thanks.

Well, you have two choices- to actually recompile all those models (which would probably take forever), or just ignore the errors. There isn’t any workaround for errors like that, and the models should still work, so there’s not much you can do- as far as I know, anyway. Someone might correct me on this though

That usually means that the modes are not from Garry’s Mod’s version of the Source Engine. You can ignore the error.
