In the time plan each text box has its own edit box under “content” when you edit it with elementor.

text boxes are sorted under “col::” and rows are sorted under “row::”.

there are 3 text boxes per row so you can see that under “content” when editing the time plan reading the different pages says;

col::

col::

col::

col::

row::

col::

click a “col::” to edit it if you need to add something to the time plan.
