when I put the cap lock on I get a capital, yet the next letter is lower case anyone give me help please.?

On Android, this is normal. To get caps all the time, press the caps key twice. If this is one a computer, your keyboard needs replacing.

in this case press shift

press shift for lower case

on what OS?

........

If you are using a computer or laptop, the caps lock is broken and y ou may need a new keyboard.  (No prob, they are cheap and you can even get them from Walmart.) 

If you are using a phone, you need to double tap the caps lock to keep it on. Also, if you change to numbers and back to letters, the caps lock will disengage.  

I hope this helps. 

Either you have been hacked or you need a new keyboard. Change your password in the program where it happens.
