Divvun sme keyboard not showing spelling suggestions

Drastic things must have happened to the spelling suggestion mechanism. The sme keyboard now in 9 out of 10 cases presents irrelevant suggestions. For "Anár" (above) it suggests Aha nu Dal. For correct "čállit" it gives čállán čállan hálit.

It seems the whole system is just broken, drawing accidental candidats from the hat. To the extent that anything is working here, neither Levenshtein nor frequency seem to be in place, let alone any tailored suggestion mechanisms (neighbouring letters, e.g.).

More data:

Input is wrong, correct in parentheses:
cállit (čállit)==> sullii hálit čállan
haliidan (háliidan) ==> blir har heive
jps (jos) ==> juo jos er <=== this is the only case where I found an adequate response, rightmost suggestion is bad, though
čáláb (čálán) ==> hálit čállán čállan

Input is correct:
jos ==> ok ja on
mun ==> Mun mus men
ipmirdit ==> (empty) mis (empty)
mo ==> eg mu er
boallobeavddi ==> boahtit boađán (empty)

It is possible that speller downloads are still turned off, due to the bug in the SJD keyboard that totally locked the phone when trying to download a non-existing speller. If that is the case, what you see might be entries from the user dictionary, since nothing else is available. Also, if this is the case, it is only visible on Android (iOS never had the SJD issue, so downloads were never removed). Try to check the speller on an iPhone or iPad, the actual speller file should be identical if available, and should thus behave the same. If it is not, it is due to factors outside the speller itself.

My i-things are at home. I admittedly have installed the SJD keyboard (both sme and sjd from the non-dev version). But users not having installed SJD report the same as me: no relevant suggestions (and it has been so for quite a long time). If the problem is a non-existing sjd speller, would then adding the sjd fst (which is good enough to be useful) fix the problem, a problem that goes beyond sjd users?
