Custom table save error

The metabox for custom table is correctly set and view only on order post

Hi,
I’ve do several test.
when I have a cpt with metabox with custom table I’ve seen this behavior:
If I have other cpt without metabox there’s nothing happened when it is Saved.
But if another cpt has only one metabox, the custom table was populate with an empty row.
when I have more metabox for other cpt nothing happened when it is saved.
Is there some bug?

Hi,
I've replicate all on a pilvia installation.

user: mbtest-admin
pass: demopass

https://app.pilvia.com/yourphpmyadmin/copper/sql.php?server=1&db=mbtest&table=wp_customtable&pos=0
user: mbtest

Scenario:

CPT test #1 -> Test CPT test #1 (metabox with custom table wp_customtable)
when I save CPT also wp_customtable was populate

CPT test #2 -> no metabox
when I save CPT nothing happened on wp_customtable

standard posts -> (ONLY ONE METABOX) "new meta box for posts" (metabox for standard post)
when I save new post also wp_customtable was populate with an empty row (only postId and AI)

Pages -> two classic metabox
when I save a new page nothing happened on wp_customtable
