I'm having an issue with KLN89B GPS. Would appreciate advice from someone who is expert.
When flying the RNAV (GNSS) RWY16 approach into YWOL and executing a missed approach after passing WOLNM, I press GOTO (WOLNH - missed approach holding point) and ENTER, then when between the missed approach point WOLNM and the missed approach holding point WOLNH the GPS flips back to the final destination YWOL rather than continuing to guide to the missed approach holding point WOLNH.
Is this normal

Am I doing something wrong?
