Edit Events Calendar Page, no column to add block

I was wanting to add an HTML block to the "events calendar" page and find no place to add content in page builder.

If I "add" a column will that work? In the picture here there are no active blocks, I want to drag my "Live Join" up...

just add a column :O)

i guess i should do this on a test site first.

going gung ho and just changing things on a whim have not worked for me in the past..

[EDIT] tried to add column, shows on page builder with HTML block but will not show up on the page..

events is a custom mod? or is it open social i do not have that installed just make a column there is a block ready to drop into it . you can just delete it not much can go wrong you haven't got anything on that page have you ?

happy thoughts

nothing else, I add column and put "Open Social" block and "HTML" neither will show
