Cloud Managed Networks

hello everyone. I want to ask the question about Basic Rates.When I create reate WLAN profile in New Central. Network Configuration is balanced.In the Picture1, Basic Rates choose 12M、24M as its basic mode.But when i create a new WLAN in Classical Central, the Picture 2 shows2.4G Basic Rates choose 1M、2M,  5G Basic Rates choose 6M、12M、24M.

WHY this difference？Can someone explain the reason why the New Central set this configuration ? Would this configuration cause any access risks? 

Classic central has all rates enabled by default.

New central has "better" defaults trimming the BPSK rates with the "balanced" option. There are minimal to no risks here.

So the New Central Basic Rates' configuration won't make stations inaccessible. And it won't make stations lose connection or others.In my test, if the basic rate sets higher, it may cause access risks. Thank you so much for replying my question.
