=== ISSUE ===
If you go to PLM > click on a primary button > click on the cog >
import records, the buttons have a `.m-1` which is added on top
of a `.gap-1`.This result in a double margin, which is not consistent
with other CP's behavior and affects the whole CP layout.
=== AFTER ===
We remove these unnecessary `.m-1`, making sure that no matter how many
buttons are shown they have a correct spacing.
