From what I’ve read from research and @Tacomaster TL, Clampett and Jones began to hate each other by the 1940s, and they started to accuse each other of copying.What would be Chuck's reasons for leaving WB after 1945?
Maybe Seltzer or who ever’s heading the studio ITTL accidentally fans the flames by giving Clampett preferential treatment. Keep in mind, Jones at this point was only now starting to hone his craft with The Dover Boys, while Clampett at this point had produced hit after hit with shorts like Falling Hare and The Great Piggy Bank Robbery - so its highly plausible.
