Hi Nick
This seems to be a bug in SAGA NextGen. I'm already looking to file a
pull request, but you could also quickly fix it for yourself by going to
.local/share/QGIS/QGIS3/profiles/default/python/plugins/processing_saga_nextgen/description/SimpleFilter.txt
and changing "MODE" to "KERNEL_TYPE" and "RADIUS" to "KERNEL_RADIUS".
You might also do it in SimpleFilerwithinshape.txt if you want that one
to work as well.
Wish you good luck
Rien

Hi berndv,
I thought we might be getting somewhere with your last suggestion, I made
the changes you mentioned and the SAGA NextGen tools duly appeared. I then
tried to run the SAGA Simple filter on a one-metre DTM, but this failed with
the message 'Unknown option 'MODE''. This is a step forward of course, I'd
not managed QGIS/NexGen to recognise SAGA at all before this. Here's part of
the output from the log:
