Ok.

So, the sequences are working correctly.

You can use sscript to catch all the output of your session and see if
someone is printing the value of Se, that I guess is not used. To make it
easier you can put something like 'Se = wowWoWwow' and search it in the
file generated by script.

After checking that the value of Se is not used then you can do several
things, for example adding \E2 q to the reset string in terminfo (keys rs1, rs2 and rs3).
You can take a look to terminfo(5) to get more information.
