Element “Post Columns” not working anymore

Hi!

Until version 5.2.6 of this plugin the “Post Columns” block (twocols.block) was working correct. It was possible to define the number of posts to be shown and also the list of categories.

Since version 5.2.7 this is not possible anymore. Adding a “Post Columns” block still shows 3 posts but editing the block only allows to change background color and font.

If you duplicate a newsletter and edit an old “Post Columns” block, it is again possible to change categories and number of posts. But if you save that block, it changes to a block of the type of “Blog Posts / Last Posts”, which looks completely different.

Can you please fix this or give any advise what to do to get this block working correctly again? We continue to work on the old version 5.2.6 but also need the GDPR adjustements made in the last updates.

Thanks,
Marc
