Mod installation problems

[b ro]

I'm trying to run some weapon stat altering modifications. So I have my .esp files in the Data folder like I know it should, and it shows up in the data files window on the launcher, and i activate the mod. But when i get in-game and look at the stats of my weapons, they're still the regular versions of the weapons. What do i do to get these mods to work?

It would help if you listed what mods you used.

my own. i altered the damage values of my .223 and 10mm pistols with the GECK and saved the .esp files in the Data folder. I also tried using 223Junkermod_v3 and ThatGunRenameCS2019 to see if mods that worked for others would work but it's the same problem.
