This solve problem with saving value, but start new. I think, Littlesat must repair check for second infobar. If is used 'None' as string and is displayed Infobar, then next OK for hide Infobar displays for a moment Second infobar screen.
It seems, somewhere is used some as
if config.usage.show_second_infobar.value:
and it must be changed to some as
if config.usage.show_second_infobar.value != "None":
