path error inserting links on units

Hi Im inserting a link in a text block in the end of my course so the student can check his grades. But when i insert the full url
and i save it , it changes the link url to ../treinamentos/conheca-a-tecnologia-irradiante/
and this get me to the worng page, actually a page that doesnt exist:

i think this is related to the same bug that i send to you about inserting images on units.

Please can you solve this for me?
