Wide bevels can be a real pain. They have a lot of surface area to spread out your honing action and on top of that you need to remove much more steel to achieve the same results. And you can't apply more pressure without limitations, because at a certain level, the blade will start to flex. But if it's a thick grind, you could try a bit heavier hand.
Other than that, it's all about patience and doing more laps, the later in the process the more. But even then, those wide surface areas can generate suction between the surface of the hone and the bevel face, with fluttering of the thinnest part as a result. (The outcome of that can be seen with magnification as a narrow strop stray scratches at the very edge) This can prevent the very edge to develop that final bit of keenness. Stropping strokes of a very light slurry sometimes help, and these edges are a great candidate for soap/wax-trick treatment (which is still in experimental stadiums, but it does work)
Finally, honing on a very narrow hone, is something that can make all the difference on these suckers. Less suction, more relative pressure.
Sorry for this rambling answer, but honing, also for me, is sometimes a matter of trying till something works. The good news is that it always does. Sooner, but sometimes later.
Good Luck,
