Uploading a font from Fontself

Hi,

I am very new to this and trying to learn. I created a font in Fontself and saved it. I then added it to photoshop etc and realised there were some issues. I edited the font in Fontself and then saved a different version. I uploaded this in to photoshop etc but it has not appeared for me to use. I tried again and it says it's already added. I'm at a loss at what to do. Can anyone make any suggestions? Thank you
