Hiding row using responsive tab does not work on iPhone

Hi
I have hidden some rows on a page using the Responsive tab. This works perfectly on my desktop, iPad and iPhone in landscape mode but in portrait mode the rows are not hidden on my iPhone. I originally had tweaked some of the Tablet resolution sizes on the Config options which caused the same problem on my iPad but since I changed these back to the default sizes, the rows are hidden on the iPad. However, the problem persists on my iPhone (but still only in portrait orientation). I also tried changing the "Type of range" configuration from "Reducing" to "Between" but this did not work. A copy of the Config page is attached. Any suggestions?

Thanks,

HI
Please try to go in responsive mode, then change the show/hide action to show it on every resolution, save your page
edit again and try again to hide it
