I found a way, sorry to be posting after 2 years but will be good for people who are also searching it on google (like me for example) :tongue:.
Use CreationKit, there is a simple explanation what you need to do:
1 - Open the program
2 - Select "File"
3 - Select "Data"
4 - The plugin window will now open, select the mod and then select "Set as Active File".
5 - Click on "Details ..."
6 - Now search for "WEAP" on the new window and note the name of the weapon
7 - Close the "File Details" window and click OK in the "Data" window
8 - In the "Object Window" put the name of the weapon on "Filter"
9 - Click on edit and "Enchanthing" put "NONE" and "Enchantment" place 0
10 - Click OK and then click Save in the "File" tab.
Sorry for my bad english.. I think :geek:
Oh I almost forgot, disenchant the item to learn the enchantment before you modify it
