Directory.GetFiles() with relative path

[stellarbear]

Issue persists when i call GetFiles method with relative path:
Alphaleonis.Win32.Filesystem.Directory.GetFiles("signatures\\yara", "*", System.IO.SearchOption.AllDirectories)

Having multiple files in multiple folders inside "signatures\yara" relative folder (for example), GetFiles lists result as if every file is located in root directory ("signatures\yara")

AlphaFS output:

"signatures\\yara\\ignore.dat"
"signatures\\yara\\apt_agent_btz.yar"
"signatures\\yara\\apt_alienspy_rat.yar"
...

System.IO output:

"signatures\\yara\\ignore.dat"
"signatures\\yara\\community\\loki\\apt_agent_btz.yar"
"signatures\\yara\\community\\loki\\apt_alienspy_rat.yar"
...
