Seems your SSL/TLS profile  uses a cert and that cert might be using these ciphers when you disable weak ciphers.

I tested this on my PA and did the commit and no issues.

 

Please check Ciphers used the certificate for SSL/TLS profile.

You can disable the weak ciphers w/ CLI commands.  This Reddit thread has a good walk-through.  When I followed it, I got up to an A- on the SSLLabs evaluation.
