L/R buttons attempt to do two different things simultaneously

[SadisticMystic]

Observe #3 in which it was noted that L/R would not be added as shortcut keys for save and load, because those buttons already had a function (scrolling between pages of saves).

Somewhere along the way, those shortcuts were added after all, and are advertised as such on the touchscreen version of the buttons. However, they still retain their original function, so if you are attempting to use L or R on a game that has five or more Checkpoint saves made for it (enough for multiple pages), both functions kick in. To whit, not only does the program prompt you with an overlay to backup or restore your save, but underneath that text box, it simultaneously scrolls the page and therefore changes what save you currently have highlighted. You would have to look closely at the faded background text to notice that a different page of saves is now highlighted, or else you might end up clobbering a different save file than you were trying to. Worse, if all your save files start with the same few characters, it may even be impossible to notice that the page has changed until it's too late, because the background text that's visible off from the side of the text box might be completely identical on both pages.

Can confirm this is an issue on 3DS, not sure if it extends to switch version. Will apply switch tag when that is confirmed.

Can confirm this issue on switch (v3.8.0). If you are selecting multiple titles to backup and navigate through the pages with L/R, R works fine but L instantly starts a new backup and also goes one page back.
