Sorry that was a stupid editing error in the mail buffer.

I tested with both TENSE pres and SF prop.

But thanks for pointing this out.

They don't and the values are restricted enough to not let this happen.

Yes I did...

Should have been:

test2_mtr :=
           monotonic_mtr &
           [INPUT.RELS  <[ARG0 [SF prop ]]>,
            OUTPUT.RELS < +copy+ & [ARG0 [SF ques]] >].

Here's a screenshot showing what's used, what works and what doesn't 
(test2_mtr is there but does not fire).

So the problem is real! Any help is mostly appreciated because that 
problem is crippling me at the moment.
