In Skyrim only 2 out of 4 enchantments are shown in Active Effects

I wanted to cast free destruction spells, so I enchanted 4 items with -27% destruction spell cost, but it seems it shows only 2 of the 4 enchantments in the active effects.
Is this a bug or am I doing something wrong?

Solution 1:

Try doing this with no mods and see if they work.

Something strikes me as odd. The enchantments are in pure, proper English but the rest of the game is obviously French.

I'm guessing there may be mod language incompatibility.

Solution 2:

It's possible this is simply a graphical glitch in the Active Effects menu.

Try equipping all four pieces of enchanted equipment and compare the results of a spell cast to the results received from only wearing two.
