Heaters is a special case, I know L-Adapter is being used for heaters, don't know about 1.1 shunt, not usually. What I would do is skip Zobel and use 100uF output and no remote sensing for heaters. Useless in a steady load as heater. Maybe it gets noise interference when Zobel for heaters.
Remember there's a resistor position in the Zobel that the electrolytic termination option needs to bypass. Watch the pads configuration.
Found it in the notes:
4. Output Zobel/Ecap
There is C104(204,304) Cout position. There an MKT & R107(207,307) form a Zobel.
That way, given the minimal ESR of a plastic capacitor, the R element stays defined as
designed in. An electrolytic can be used also as per BOM, in that case the R107,207,307
position MUST be shorted with a jumper. It is speedier using the Zobel, plastics are more
linear also, still an Ecap is sometimes needed since it has bigger value and gives more
damping if a load is much reactive or has unpredicted parallel parts on its rails,
like very small decoupling elements, should you will notice instabilities cooperating with
the reg. If there are no problems even with heavy current loads, the MKT + R is best.

Could be the heater because it has inrush at startup overshoots the current limiter, output voltage drops, and nothing works normally for a little while until its mA current demand goes to spec.
“An electrolytic can be used also as per BOM, in that case the R107,207,307

Did you do that?
position MUST be shorted with a jumper"
Did you do that?
When remote sensing is defeated there must be permanent jumpers configuration for that mode. Not allowed to be powered with sense nodes not closed to force nodes.
Salas fixed, I'm sorry was the wire with enough section. Trusted the seller as tester silicon wire up to 1000V 1x0,50mm2 (20AWG) so 2.5A. Is this one https://emelec.es/wp-content/uploads/2015/01/Q2-205.pdf
