I used to have the same problem with ListView until I added support for controlling focusability of the listview and the contained entries to my engine built from source.
One function I had to change was the implementation of SupportsKeyboardFocus in SObjectTableRow from
virtual bool SupportsKeyboardFocus() const override { return true; }
to
virtual bool SupportsKeyboardFocus() const override { return bIsFocusable; }
Of course you’ll need to add that as a new member to the class, the FArguments and the Construct function. And then you also need to make sure the ListView passes its setting on to any of the generated entries that are created in UListViewBase::GenerateTypedEntry.
