Table cells inside a landscape oriented text frame become unselectable
I'm not sure if the title clarifies my problem. I'll try to explain what I did until this point and then ask for some guidance from the community.
This is the original page on Indesign.

This is what I've done to incorporate the same structure on Framemaker.

My master pages have portrait oriented text frames by default. I've inserted another text frame inside the main text frame and rotated it 90 degrees counter-clockwise. Then I've inserted the table inside of it.
I've changed the Run Around property of the landscape oriented text frame to "Run Around Contours" to be able to place it in between the lines inside of the main portrait oriented original text frame.

Up to this point, everything went well but right now I can't select the cells inside the landscape oriented table with the cursor. FM selects the whole table when I click on it as if I have pressed on the "Select Object" button. I have to point into the top line inside the landscape oriented text frame, then press the down arrow to enter the table and then browse the cells one-by-one by using the arrow keys. I can't select more than one cell by pressing any keyboard combination inside of the table. Shift + right arrow allows me to only select the complete line inside a single cell.
Maybe my complete workflow was incorrect or I'm missing something crucial here.
Could someone guide me on how to solve this issue?
