Adding bone constraint changes bone alignment

Here’s the problem. I gather it’s a common one but I can’t find a way to eliminate it. The pose position has had all rotations and translations cleared. There is an IK constraint on the shin bone and it has a pole target. Can anyone help? Thanks!!

You changed the bone target position for the ik bone in edit mode/rest position.
Just move the ik bone tail to the ik bone target head or vice versa in edit mode.

Yyeesss!!! Thank you !!!
