Problem with sizing object's outline and text

when i made a rectangle and try to set the outline to 5 pt and then press enter, the result will not be an exact 5 pt outline. instead it set to 500 pt. and if i set the outline to 0.5 then the result would be 50 pt. it's just like there are always 2 extra 0s in whatever size i am setting. 

this is the almost same to text size as well. if i try to set the text size to 20, the text size would show just 2, without the 0. but it is bigger than 18 sized text.

i have already try the "press F8 when starting corel draw" to reset to factory setting. but this still happening.

can someone help ?
