Upgrade version problem

[mr-wolf-gb]

I installed aaWAF with command : URL=https://download.bt.cn/cloudwaf/scripts/install_cloudwaf.sh && if [ -f /usr/bin/curl ];then curl -sSO "$URL" ;else wget -O install_cloudwaf.sh "$URL";fi;bash install_cloudwaf.sh
the installed version is 1.0 but in release there are version aaWaf 6.8 and the installed version not the same in screenshots

how to upgrade because using command btw 17 start upgrade but always upgrade done to version 1.0

I tested this on my waf server and the command tell me if you want to upgrade run btw 17 else will clear config and run new install, but in the 2 ways the same result version 1.0
