Intumisent seal between frame and structure

I'm working on a FRA in a 10 year old apartment block, various blocks maximum 6 floors high. Fire door upgrades, mostly reducing gaps on fd30 doors (120 number) when the door gaps cannot be achieved by fitting hinge packers we sometimes remove the mdf 18mm x 70mm architrave s to wedge the frame into position. We then seal the gap between the frame and the structure with intumisent mastic and fire batt if the gap is above 15mm. Should we be removing the opposite side architrave s and sealing from that side also.

Then knowing that all of these frames has no fire stopping between the frames and structure,  should we not be sealing every frame
