According to ESPN, which cited unidentified league sources, the 29-year-old forward has "aggressively challenged coach Brett Brown on his role in the offense".
Butler has reportedly challenged Brown about his role on offence, and was even classified as "disrespectful" by witnesses during a video session in Portland last week, in which the situation allegedly escalated to a point "beyond player-coach discourse".
Butler hopes to play in more pick and roll sets on offense as opposed to finding his shot in the flow of the offense, according to the story.
However, Brown told people within the organization he didn't have any issues with the exchange, and it's simply part of the relationship he has developed with Butler, ESPN reported.
The Sixers, 25-14, acquired Butler via trade with Minnesota in mid-November, and they are 14-8 since the deal. According to ESPN, Butler's struggles to fit into the Philadelphia environment have caused some worries about whether he'll fit into the team's longterm plans, though the club is adamant about making the Big-3 (Butler, Simmons and Embiid) work this season and beyond.
The report added Butler is aware that "his intense, direct style can come off as combative as he is trying to make clear his viewpoints".

The Knicks later said Kanter will not be able to make the trip because of visa issues. "That will be a very ugly situation". But just because of that one lunatic guy-one maniac, one dictator-I can't even go out there and just do my job.
That landed him in Philadelphia where he must now compete with two other full-blown stars in Simmons and Embiid for touches.
"What's most - by a mile - lately, on my mind, is the growth of a team, and the cohesion and the ability to share in somebody else's success", Brown said after Tuesday's victory over the LA Clippers. "We have a new opportunity".
There's always a feeling out period when acquiring a new player, especially in season.
The Jimmy Butler-Timberwolves saga had gently settled after his move to the Philadelphia 76ers, but it seems like Butler is taking trouble everywhere he goes. "That's why I lost it", Embiid said.
