editor.setComponents removing the blocks with same tagName after upgrade

[vindu25]

I have updated to the latest version of grapesjs i.e 0.21.2 earlier we were using 0.15.9, post update we noticed that the some of the blocks of the template are missing upon checking we found that editor.setComponents() kind of removing all the duplicate blocks with the same tag name.

I can still see them under _firstAdd of DomComponents

The following is our block structure for the template which we are setting in editor.setCompnents . Any help would be much appreciated as running out of ideas on why this is happening.

I went through the previous releases till 0.19.5 I can see my old code changes are working fine, from 0.20.1 it started breaking.

There are a lot of components with the same id, that's the problem
