Drupal Core 8.7 views & panelizer

I was using Drupal 8.5.8 & contrib modules Panel & Panelizer. I was created the views blocks with some contextual filters and assign these blocks using panelizer on a node. These contextual filters was showing with empty options. I was added the options by form alter.
Now i have upgraded the drupal core 8.7.2 & these contextual filters are not showing in panelizer settings.
