Leaf2 ,v3.5.3, Scrolling not working on two 3rd party apps

On my Leaf2, I am using two news apps.

Independent https://play.google.com/store/apps/details?id=com.feedhenry.fhjjjn7In7fqJG2LHTv3LVLanX

Irish Times https://play.google.com/store/apps/details?id=com.irishtimes.newsapp

The buttons are set to scroll up and down on each app. The down scroll works fine.

The up scroll will not work in either app. Is there any way to get this to work, or is it how the apps were developed?

All other apps scroll work fine. Appreciate any help.

Thank you,

Darren.
