    That should be fine. The Barometric draft control should be straightened up though.
    Who ever did your last professional adjustment on the draft control did not get an accurate draft adjustment, and therefore your combustion adjustments can not be correct.

    If you did a DIY chimney inspection and put it back that way, the combustion adjustments are now way off.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Code requires 6" clearance between single wall flue and combustible materials.

    Is Fiberglass insulation Combustable material?

    Easy solution
    Cut the insulation back 6" from the vent.
