Removing diverter valve on free standing tub faucet

[Jfspartners]

I have free standing with leaky diverter valve that is used for the hand sprayer. It leaks all the time so we do not use the tub anymore. I can't figure out the manufacturer of the faucet and I tried to take out the diverter to fix it and for the life in me can not figure out how to get it out.

Any help would be greatly appreciated!
