Unable to Dual Boot Windows and Catalina

Hi Guys, i have two OS's installed on my system. Windows 10 and MacOS Catalina. my problem is on the OpenCore boot screen i only get the option to boot Catalina and to boot windows i either have to use the F8 boot option or change the boot order in the BIOS. does anybody have the same issue or have a fix for this. ??
Thanks guys....!!
