This is my bike, from 2016 -- first thing I changed back then was to replace the original flat bar with a riser bar. I've modified several things since: different saddle; Nitto albatross bar with Shimano bar end shifters; 130mm horizontal/0 angle road bike stem; different wheelset with 8-speed hub and MicroShift cassette.

The left/front shifter went bad first in 2016, skipping across the middle chainring. I replaced it with a cheap SunRace SLM10 friction thumb shifter. The right/rear shifter went bad after I was hit by a car last May. It worked for awhile then quit. I was switching to albatross bars anyway and bar end shifters work better with that setup. The old Shimano thumb shifters are in the junk box in case I ever get the urge to try to fix them. Degreasing/degunking didn't help.

This is another BF member's identical mixte version, same year, paint and components including the indexed shifters.
