I am attempting this build, started off cleric, then adding monk, but the unarmed strike is only showing the standard strength damage, not the monk (DEX) damage. Is there anyway to correct this?

Side Note: The AC was adjusted using the monk base AC, so at least that portion is correct.

If your Str is higher, it will use that instead of Dex. It uses whichever is higher.

If you are wearing armor or wielding a shield, you will not get the correct AC or movement.

Dex is much higher than the strength.

You have a shield equipped. Shields disable Monk's Martial Arts ability. They disable the Unarmored Defense of the Monk too so instead of 10+4(Dex)+4(Wis)=18 AC you've got 10+4(Dex)+2(Shield)=16 AC. So your shield is completely detrimental to you. Get rid of it.

You gain the following benefits while you are unarmed or wielding only monk weapons and you aren’t wearing armor or wielding a shield

Unarmored Defense

Beginning at 1st level, while you are wearing no armor and not wielding a shield, your AC equals 10 + your Dexterity modifier + your Wisdom modifier.

Shields (and armor) are kryptonite to monks. No bugs here.

You are all correct, the shield was the issue,, thank you!
