Big Times Draw Poker RTP question

On Wizard of Odds site, Big Times Draw Poker 8/6 Jacks or Better is listed as 0.9548 rtp where regular video poker 8/6 JOB has 0.9839
rtp. 7/5 Bonus poker is listed at 0.9846 rtp where regular video poker 7/5 Bonus Poker has 0.9801 rtp. My question is why is Jacks or Better rtp so low in comparison to Bonus Poker when the rtp of 8/6 Jacks or better in regular video poker is higher than 7/5 Bonus Poker? Is the 0.9548 for Jacks or Better in Big Times Draw Poker a misprint? Seems like it should be better than Bonus Poker

I don't think it's a misprint.
The multiplier structure strongly favors premium hands, like dealt AAAA2 or 22233, which simply aren't premium in Jacks.

I reviewed the game on videopoker.com and found that the multipliers in the 9/6 JoB version are significantly higher than those used in the 8/6 version for analysis. According to regulations, the RTP (Return to Player) of any additional betting feature should be at least equal to the RTP of the base game. It’s possible that WOO may have incorrectly applied the multipliers.

Additionally, there is a specialized pay for a straight flush in JoB, Bonus, and Double Bonus Poker games, which seems to have been overlooked by WOO.

Thanks sza and dieter.! I have just recently started playing it with bonus credits bet. I cycle freeplay through it sometimes at the 5 credit level because there isnt anymore 9/6 JOB at my locals. Im a member at VP.com so I will search it on there too
