Export font is wrong name

i had a project Pearl1.fcp, in Font Properties i named both the font family and font full name Pearl1

when i do File Export Font i get
Pearl1.TTF
so far so good, everything as expected and wanted

but now i do a Save As for the project as ICON2.fcp

in properties i changed Font Family and Font Full Name to ICON2
now when i do File Export however it still makes the file Pearl1.TTF !

i closed and started over, same thing, only the new ICON2 project is open, i can’t find where the “Pearl1” name is being stored
can you help?
my version is latest

Edit the Export Settings for the new project. The *.ttf or *.otf or *.woff filenames are stored there for each project.
