Schematic for LDO incorrect / wrong part number (ST1L05CPU33R)

I tried assembling my first nanofoc yesterday and I think I might've found a small mistake in the schematic or in the part listed.

The LDO is an ST1L05CPU33R, which is listed under ST1L05C in the datasheets. This version of the LDO has an enable Pin, which is not connected on the PCB. I was able to make a small bridge to the capacitor right next to it, which successfully enabled the 3.3V output.

I believe the part should either be an ST1L05 (without the C) or there needs to be another connection to this chip.
