Ok, a little closer, I was able to get the field save in the new flexible content field that it gets moved to. However, the field’s value does not get saved.
I modified the code in the .acf-hidden input so that the page element’s layout gets updated in this format:
acf[column_field_key][1][elements_field_key][2][acf_fc_layout]
I changed the column number from 0 to 1 to move the page element from the first column to the second.
