2002 corolla front right bulb not flashing [solved with switch the light bulb]

Hi everyone! The front right turning light of my corolla stoppped flashing when I push the turn signal switch up or press the harzard switch. However that light can illuminate when turn the switch to side marker. The turn signals in car still flash. I tried to replace the flasher but it doesn’t fix the problem.
Is there any other thing I can do with it?

What’s the explanation that it worked ok in “side marker” mode? Different bulb or filament for that?
