I'm sorry that you ran into trouble with this. I've confirmed that the font selections you mentioned are added to your account correctly. To make sure that I understand: all the other fonts are showing up in the Fonts tab of the Creative Cloud application? Only Muscle Narrow & Wide are missing?
If you haven't done so already, would you please try turning off font sync in the Creative Cloud application, wait a moment, and then turn it back on? The option to do this is under the gear icon in Preferences > Fonts ("sync on/off"). Sometimes the app just needs a fresh session for the fonts to appear again.
If that doesn't make a difference, please send your recent sync log files to firstname.lastname@example.org so that we can take a look. I'll include that information at the end of this email.
On OS X:
* Open the Finder
* under the Go menu, select "Go To Folder"
* in the window that opens, type: /Users/(username)/Library/Application Support/Adobe/CoreSync/
Remember to replace "(username)" with your own account name.
(Or if you are comfortable working from the Terminal, cd to $HOME/Library/Application Support/Adobe/CoreSync/)
Attach the 3 or 4 most recent CoreSync-yyyy-MM-dd.log files to an email. Please don't send a zip file, as they often get flagged as spam.
Turning off and turning on the typesync function has not solved the problem so I sent you (by email) my three most recent CoreSync log files. Trusting you will be able to detect and resolve problem.
I wish to thank you and your team at Adobe for the great job in helping me to resolve the subject issue.
