Experiencing problems with Save as PDF Macro in Word

I've created two macros to save Word files as PDF's. The first one is designed only to save the Word file as a PDF without overwriting any existing PDF. It's giving me two problems. First, when it gets to the "Save" button, there's about a four-second pause before it finishes. There's no such pause needed when I do this manually—as soon as "Save" appears, I can immediately click on Save and I'm done. Second, sometimes it goes beyond what's specified in the macro to do a "replace existing file", even though the macro doesn't specify this.* When it does this, it sometimes goes back to the Save screen and stalls there.

*In addition, bizarrely and concerningly, after setting up these macros, it now sometimes does this behavior even when I do the procedure manually, something it's never done before.

The second macro is designed to do save-as-pdf, and then to overwrite any existing pdf. Here I have the first problem noted above, namely the four-second delay after the Save button appears. In addition, sometimes it stalls at the Save panel, giving me a KM error message saying it couldn't find the needed button.

The 4-second delay may be due to this, which doesn't reach this CPU level when I execute the actions manually:
