Vitaly from TCA.by

Yes, @jakept , I know that I can’t.
I thought may be is any alternative ideas instead of copy child theme and lost future updates there.
Thank you for your quick answer!

@tw2113 am I right that your CPT UI hasn’t own table(-s) at the database?

I’m looking throw MySQL database and can’t find any transformed records. I’m afraid that my first description was not fully correct. Old CPT record removed :(( the new one (that I tryed to add today) – yes, transformed to native POST, and without any special data (because special data should be applyed only to this CPT (at ACF Pro setup). So it looks like a lost.

I’m going to move this site to production and will try to apply your last paragraph (I will need to move the site manually in current situation; empty WordPress…parent theme…my child theme and so on)

I worked on Tuesday, and no any troubles with this CPT. I got free day yesterday. I had troubles with Search Results template (looking answers at Elementor Pro and on the forums) and  I started today from Elementor & Search Results decisions. 
Then I updated some plugins (and CPT UI also).
Then I click on the ‘Solve problem’ link near Elementor (on the plugins page), because I thought it will affect on Elementor & its support only (I never use this functionality ‘Solve problem’ before). I clicked back (browser) and switch off 'Solve problem' mode. 
CPT UI show me 'need update' again, I click on it but get warning that I have fresh version.  

After it I started attempts to roll back my site from backups, but nothing.

Just now: screenshot how to my CPT looks after self-conversion

=header menu
I lost ‘m’ in previous

I will move the thread there are you agree?

Yes, will continue here, I think.
https://yadi.sk/i/Zd88JBVTC9WOuA – this is a previous setup of the header small menu.
https://yadi.sk/i/_h-j6hcL-FE1Vg – this is the current.
https://yadi.sk/i/DQ8O20_HPYvp3w – and this is the dashboard, Menu Setup, header enu that doesn’t appears now.

https://pastenow.ru/7b18c3756804cbb551e961e6a6f84397 – you can see that in block editor ‘more’ is presented and visible

And More tag isn’t working ??

How to fix?

@nitushrestha10 I’m sorry, but what about those bugs? It was appears after the theme update

Thank you, Nitu, for the help.
The new problems (2) after the theme update.
I’m using
* @package ThemeGrill
* @subpackage Spacious
* @since Spacious 1.0
and did update at 17/09

The first bug is: The main menu action button simple text gets http at the start, and %20 instead of spaces. We was need to create small crunch to fix it.
I mean: text ‘Оформить заказ’ was transformed to ‘https://Оформить%20заказ&#8217;

The second problem is more seriously, we can’t find and fix it – the menu ‘Header’ isn’t appears. No any setup were changed. Before update it was shown, after – none. How to fix it?

@nitushrestha10 Could you help me?
