Round Brown Spots on Grape Leaves

The leaves on one of my grape plants is starting to develop brown spots. Please see photos. The plants are thriving but I am afraid this condition will get worse and spread and severally damage the plant down the road. Can you tell me what this is and how to eliminate it? Tiny grapes are finally starting to grow but I don’t know if this condition will eventually hurt the plant. Should I just cut off the affected leaves as they become affected? Thanks for your help.
