Abowser and Icecat both edit file listings

The domain I'm working on has a folder with a lot of files and sub-folders in it. I can see all of them with FileZilla and with Cpanel's FileManager, but Abrowser (and Icecat as well) won't show some of the sub-folders.

I temporarily "solved" this problem by moving the "invisible" sub-folders to a new location, whereupon they become visible again, so they're not figments of my imagination.

My ISP's browser (didn't say which one) sees all the folders, so it's just Abrowser and Icecat which edit the listings.

Is there some place in Abrowser's settings where I can select the format of file listings at a given URL ?
