Help me revert my "bold" underline back to normal

Hi everyone.

Okay so to clarify, I took a screenshot to explain what I mean by my "bold" underlines:

Notice the difference between the bold underline and the normal ones. There is also some weird thing happening where in some cells, when I use the underline feature, it shows as a bold underline, but once I've pressed enter to move on to another cell, the underline reverts back to normal. If I select to edit (F2 or double-clicking) said cell, the underline becomes bold, and vice versa (s3lw.png).

All this started happening immediately after I did this (was just experimenting, and I have no idea what this actually does, or if it was the cause of those occurences): Insert > Symbol > Special Characters > No-width optional break. I did that to just one cell though, and now all this weird stuff is happening. Help me fix this please!

Select the cells that exhibit this behaviour and click on Clear, Formats. (Found on Home tab right side of ribbon)

It simply removes the "wrap text" and text alignment. The words still show a thick underline while in the selected cell.

Have you by chance changed the font in the process that you went through to get to this point? Check the font when one of these misbehaving cells is selected.
