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.

Run the following commands on in the cli at the edit prompt.
then commit

set shared ssl-tls-service-profile (select your security profile here) protocol-settings keyxchg-algo-rsa no
set shared ssl-tls-service-profile (select your security profile here) protocol-settings enc-algo-rc4 no
set shared ssl-tls-service-profile (select your security profile here) protocol-settings enc-algo-aes-256-cbc no
