Some Google fonts don’t work

Trying to change the font on the testimonial title in the slider using the customiser. Standard fonts work. Google fonts show up in the Inspector as the correct font but do not display as the correct font. I tried downloading the google font, converting it to a web font with all of its types and using Elementor to make the font available. This worked with a different non-web, non-google font, but not with the google font. The code I used:

.testimonials-widget-testimonial .list-title {
    font-weight: bold;
    font-family: 'Kaushan Script';
    color: #ffffff;
    font-size: 30px;

When I changed the font to:

.testimonials-widget-testimonial .list-title {
    font-weight: bold;
    font-family: 'Bernard MT Condensed';
    color: #ffffff;
    font-size: 30px;

the font displays as Bernard MT Condensed.

How do I fix this?
