Odd uneven spacing between some words in Indesign, unable to adjust using paragraph styles pannel

I'm having problems as Indesign acts kinda stubborn. It keeps giving me an odd space between a word. I've tried to readjust the spacing using paragraph styles, font size, changing the font, spacing, leading as well as tried to re-adjust the width of the container. Unfortunately none of these attempts have resulted in any success. Can you please give a hint ? I have a very important project that I want to finish as soon as possible.
