vgPattern is not selecting correct volume group

[w3aman]

What steps did you take and what happened:
[A clear and concise description of what the bug is, and what commands you ran.]

• Created storage class with vgPattern as lo* for my volume group starting with lo initials.
• volume should have been created from this volume group but it was created on a volgroup named lvmvg

spec:
  capacity: "48318382080"
  ownerNodeID: lvm-node2
  shared: "no"
  thinProvision: "no"
  vgPattern: lo*
  volGroup: lvmvg
status:
  state: Ready

here vgPattern doesn't match in volume group name still this volgroup was selected for creation lvm volume

Yes, it was correct working.
Actually lo* regex will work as first l and then zero or more occurances of o
so it took l and zero o this time so pattern become only l and which is obviously a substring for lvmvg
