ES disappeared?

Hello, I have a lvl 81 Witch and use EK build.
I was using the following skill tree points: Eldritch Battery (consumes first her ES and then consume their mana), Mind Over Matter (when taking damage, 30% will be taken from your mana) and Zealot's Oath (regeneration of life is applied to ES and non-HP).
I had at that time 1668 ES, 2040 with lvl 11 dicipline
I decided then reset these points to do some testing, my tests have failed, then I returned the points as they were before. Surprise! I returned with ES 800 and only 1000 with dicipline! I do not know if I did something wrong for this to happen, as the case, tell me what have I done.
If it is a bug, I await a response from GGG unfortunately do not have a screen shot taken before the event, but it really hurt my character and for sure I will have no right back my dear ES! What to do?

PS: sorry for my English, I know he is a little bad.

Have you actually tried working out what you would have?

You don't have an awful lot on your gear, and you don't have any passives buffing your ES on the tree.

You don't have mind over matter

AND you have Acrobatics
