ENH: Tons of fix:

- SQ not declared as SQ
- Regular Element declared as SQ
- Element not retired
- Element missing
- Waveform problem rappear (I swear I clean them already)
the 50/60 needs to be update to propagate the RET thing... too lazy to do it.
- Update some name (missing s, missing Overlay...)
- DS declared as CS, vice versa...
