Font changed abruptly within WordPress

Hello. The font size within my WordPress changed suddenly. Nothing to do with my website font. My WordPress dashboard as a whole looks different from when I first installed it a few days ago, along with the Flatsome theme. Everything was moving along just fine until yesterday.

I don’t know for certain but it may be that I went to ‘Appearance’ then ‘Customize’ and then back out again without changing anything. Perhaps it is something else.

This font change has also affected WordPress’ functionality by limiting access to certain options. For example, not all animation styles are given under the UX banner. Before there was a long list of options than included ‘flipinX’/’flipinY’.

Please help.
