In List of Figures, "Figure" and "colon" are disappeared when changing gap between Figure Numbers and Caption

Question

I have found the question Numbers too close to figure captions in List of Figures, can this be fixed without changing the class? very helpful to add some spacing in List-of-figure in a Report document. But one thing I want to ask that while doing this, now in generated LOF the the word "Figure" is missing and also the dot is replaces the colon ":" Can anyone please suggest how I can fix these two things (Figure X.XX :) in my LOF while maintaining the same spacing.

Thanks
