Looks normal to me. You can see the ridge where the tendon feathers into the muscle in both.
I dissected a woman last year though that had three headed biceps, variations do happen.
Some muscles such as palmaris longus, psoas minor, rhomboid minor, pyramidalis, zygomaticus minor, and adductor minimus are optional and not found in all individuals.
Tendon slips vary often in attachment points and number as well. I have a specimen right now that has tendon slips in both his coracobrachialis that extend all the way to the medial epicondyles of the humerus.
Nothing to worry about.
