Spreadsheet - Error when typing percent cells

I tried to enter percent cells in the spreadsheet. I typed:

  • “19” - Just fine the cell became 19.00
  • “19%” - OK again, acceptes as 19.00%
  • “19” - (no percent again): got 1900% instead of 19.99

Apparently
after the first entry concluded by a percent sign
all typed cells are assumes as percentage.
