mrstee on "[Plugin: WP Tiles] bug? after adding new grid, impossible to use other grids for galleries"

What a beautiful plugin with so many features - unfortunately since creating a new grid I cannot change the grid of galleries anymore, and grids in different posts are all shown in the same grid in spite of different settings.

After I added a new grid that I made with the editor (amazing how intuitive the user interface is, I love it!) and changed the format of one image gallery to this new grid using the dropdown menu in "Edit post", all other galleries in other posts or on other pages were also suddenly displayed in the new grid. They looked like the new grid although in the "Edit post" menu, the previous grid (News) was still listed.
Moreover, I could not correct these changes because it is now not possible anymore to change the grid for any of the galleries. I can select a different grid in the dropdown menu but this does not have any effect.

The only solution for me to get rid of the new grid was to delete it (in the WP Tiles settings, Grids, list). However, after that the plugin picked the grid at the top of the list and transformed all posts into this format, again ignoring the grid that I had specified in the menu. I went on to delete all grids and then step by step add new ones, but the galleries seem stuck with the one on top of the list.

I have to say that I do not know how to work with shortcodes. All I did was to add a gallery and click the check for "tiled gallery".
Creating a new grid seems to have removed my ability to change the grid of galleries using the dropdown menu, and to have different grids in different posts. This seems to be a bug, so I wanted to leave a report. I will post if I find a work-around.
