hide currency flag from heading

hi, first of all thanks for this amazing plugin, i’m planing to buy the pro ver. but however i need some customization, want to know is it possible in pro ver.

im using “Flag + Currency code” design

want toi hide the flag from the header, which i did using the css (.wmc-current-flag{displa:none;}), which is working fine, but the issue is when we select the any other currency from drop down and page reloads, for brief period of the time it shows the flag again, so i want to hide this also

tried to find out the css selector for this but not able to do so, can you help me on this.

thanks in advance
