Trying to instal custom fonts

Trying to instal some custom fonts in a project, while they display perfectly in the job when I preview or export while the weight is correct the actual font is wrong. I can’t seem to delete them either to try to reinstall. I use them successfully in the Muse version of the website. Any thoughts please. The font is Century Gothic and the files I’m using are for example 2F47B7_0_0.woff2 which is Century Gothic Regular.
Thanks in advance Jane

Sometimes while I’ve been trying to do this, the font appears as OTS derived Font???

Hello @JPuttock, as mentioned over email, please share the website address so we can look at the issue.

Sparkle generates the necessary web fonts regardless of which font file you give it, so that shouldn’t be a problem.

The test site I’m working on is Page 1
