Ford Fiesta S 1.6 2012

Last week, when I started my Ford Fiesta S 1.6 2012, it showed a check engine, traction control light, and hill start assist on my dashboard. The RPM of my car has been unstable.

I have a portable scanner and returned a P0351 Ignition Coil A Primary / Secondary Circuit error. I had the ignition coil replaced at a local mechanic. After replacing the ignition coil, the misfiring seems to be fixed:

But when the mechanic had it scanned again, it showed two more errors: U0401:00-2B and U0401:00-2F

Has anyone encountered the same problem? And what did you do to fix this?
