Hello,
Install the mentioned extension and it will clear cache together with page re-loading just by clicking https://prnt.sc/26w3x76
About “Text Transform” in the header, you need to change it via Theme Options > Header builder > Top header – https://prnt.sc/26w3y5f (set None). Also, change “Content Zoom (%)” there, to change the Font size.
Then you will get the same https://prnt.sc/26w3z3w you have in the static block https://prnt.sc/26w3zc4
