@crystalmcc. When you have a theme or plugin acting strangely, it is very frequently a conflict between your theme or plugin and another. One of the very first steps is to deactivate other plugins, including the one you are having trouble with. There are two approaches to doing this that I have found helpful.
1) Deactivate all of them and then activate one at a time.
2) Think back to any recent updates prior to the problem. Deactivate those first and then retest.
Over many years of using WordPress, I have identified countless problems this way.
The next thing is to make sure all of your plugins are being actively developed. Often we use free plugins and then the developer discontinues developing. I have no problem using free plugins when they are available, but just know that it is important to keep current plugins. Often, it is old code that conflicts with newer code.
That’s my two cents.
