There are three buttons on the right side of the "All Fonts" column, and the rightmost one is an upward symbol. Click it to hide the cloud font. It's strange why this button is not placed in the column of cloud font. Maybe there is a change button on it. I was also troubled by this little question, and then I found that there was no reliable answer. I just looked at it carefully, and the button was right under my nose. )

Click the symbol on the far right to hide the cloud font.
