You mean besides the fact that the producers didn't want to permanently end Bruce and just have Hulk? In his early appearances, Langkowski could transform back and forth at will. This aspect could have just not been shown on X-Men and Hulk and Sasquatch merely had his conclusion wrong. The comics also said that Langkowsi's experiment opened a hole to the Realm of Great Beasts and his body was invaded with Tanaraq who is the one that really gives him his powers. The experiment on the show could have affected Tanaraq's relationship with Langkowski and since Bruce has no connection to the Realm he was unaffected. The best in-series explanation would be that the experiment simply affected each man differently.
