I'm new to the program and i have only learnt what i needed to do for work, but i have been given a new task and i've gotten stuck.

I have been given a page which is the block and i need to edit this block as the information to go into it has changed.

In the block editor I get 10 rows of info each with 7 collumns.

 

 

(its petrol station information)

 

I want to add an extra row onto the bottom, so i copied and pasted the last row and placed it below. I change the attributes so they all say 11 instead of 10

 

 

but the main properties were still the same

 

when i close the block editor i cant see row 11.  Am i missing something? Like i said i didn't make the block so i'm not sure exactly what to do.

 

 

If you need more info let me know and i'll do my best to explain.
