Describe your issue

After selecting a specific folder as the default install location, the installation path changes from the expected E:\WinGet\xxx to E:\WinGetxxx. The slash / between segments appears to be ignored, causing the path separator to fail. The default setting does not allow fixing this slash issue. I also tried the standalone package install option (where the install location can be edited manually); after changing the install path to E:\WinGet\xxx manually, the package installs correctly to the expected directory. This bug appears to be caused by the concatenation behavior in E:\WinGetBit/%PACKAGE%, where the / before %PACKAGE% is ignored or not recognized as a path separator.
