I made a mod called AROP- Bosmer Edition, and made the command animal power a lesser power. By putting the spell type as lesser, in the spell menu. But when I use it in game it says "Powers can only be used once a day."

Here's a pic of how I have it setup:

Does anyone know what I did wrong?

Try to use an existing lesser power as night eye as base then change the magic effect.

Two thoughts. I have set up lesser powers with out this problem, but never used them as a voice equip type. Maybe that has something to do with it. It could also be something related to the effect and not the spell.

I tried making them cast from either hand, and I still have the same problem.

Here is a pic of the vanilla Magic Effect which I use for the lesser power.

After checking and rechecking I'm 100% sure that this message should not pop up if the spell is set to a lesser power. Only regular powers do this.
I see that you have it set to lesser power. Perhaps you had it saved as regular power at one time and it is stored in your save file. You could type in your console:
Help Animal
Then find the form of the spell. Then type:
player.removespell xxxxxx
Then
player.addspell xxxxxx
Where xxxxxx is the form the help command says your spell is.

I've had issues in the past with old spells overwriting new updated ones and this fixed it.

A clean save may work also.

Thanks for the reply Spinner. But I figured out what I did wrong. When I made my version of the power, I forgot to give it to the Bosmer. They still had the vanilla version, which is set as a greater power. Now it works as it should.

Thanks to everyone for their replies.
