Trees like this are made en-masse in south Asia and then quarantined and sold to garden centers and supermarket. That's how the term Mallsai came to be. That's also why we try to avoid obvious S-curves, as it might hint towards your plant being one in the past.
Anyhow, yours looks fine. The damage can be seen as character, as it tells a story of what once was there but no longer is.
Over time, those lumps will be overgrown by new bark and they should become less visible. But depending on the speed of growth, that could take a decade.
