Contact Lens: toric, colored & circle: Astigmatism Correction in one …

So i had my eyes rechecked after not seeing well with original Rx (first time glasses wearer). I have a slight astigmatism in left eye. Right eye is fine.So the doctor made a slight change in the Rx. Right eye still was fine. When i received the glasses back , the owner of the store said “We put a little power on the Right side to balance it a little”.Is this normal? especially since the Doctor did not write a prescription for the right eye? It is very minimal, but it very slightly degrades my distance vision in the right eye. Overall the glasses are much better now and i don’t feel disoriented as a did before. The doctor said I can wear these for all around purpose (i believe he is unaware of any change in the right eye lens). Just want a professional opinion on this matter.
