I tried and find the way to solve it. Hope it helps.
1) Deactivate “Admin Column” plugin, then can edit post type by bulk.
2) If the issue caused by “Admin Column” plugin, then go to “Admin Column” plugin setting,
add “Type” as one of the column item. (“Type” means Post Type)
After doing that, “Admin Column” plugin works and can edit post type by bulk.
the solution is from this post: https://www.ads-software.com/support/topic/bulk-option-doesnt-appear/
