Change the order of the sidebars

Somehow I started to experiment with the settings under Action tab and lost the original order.

But now I can’t add another widget (Read the Super Radiance) by merging under ‘Baskinta’
and also can’t add ‘Recent posts’ widget by merging under ‘Read the Super Radiance’
Are there any limitations how many widgets can be merged under another one?

In any case this merging for the purpose of adding is not solving my original question because I would need to reorder/add different widgets in different order on different pages, so binding them by merging under specific other widget wouldn’t work for the whole site.
Any suggestions how to do this?

Also, why are some widgets no more available in the ‘Quick select’ in the Edit mode of the page?

Now after some more fiddling I got this structure (see the image):

but out of 6 widgets only 2 are visible on this page:
https://wpg.meditationyoga.in/world-peace-through-meditation-2/

and in the Edit mode of that page I can see that only 2 more widgets are available to choose which makes sense since the others are in the Merge mode – see the screenshot:

But how to fix it so that the remaining 4 widgets in Merge mode will show up?

I deactivated all other plugins and still the remaining 4 widgets did’t show up.

Now I managed to get 5 widgets visible on this page:

https://wpg.meditationyoga.in/world-peace-through-meditation-2/

See the new structure of the widgets in the screenshot:

I merged ‘Search’ widget under ‘Donate’ widget and had to merge ‘John Hagelin’ widget also under ‘Donate’ widget otherwise it wouldn’t show. Then the ‘BASKINTA PEACE PROJECT’ widget merged under ‘John Hagelin’ widget and finally the ‘READ ‘THE SUPER RADIANCE EFFECT’ widget under the ‘BASKINTA PEACE PROJECT’ widget. Then there is 1 more widget that is supposed to be there – ‘Recent 7 posts’ that is actually the default WP recent Posts widget and that is refusing to show up.

So from this I see that mixing the default WP widget with the custom ones is not easy, maybe not possible or maybe it’s a bug, or maybe I have missed something? If I have missed something please let me know.

OK, no answer so far…
Well, I found now much better plugin, much simpler to work with and does the same job.
