Map Towers

I'm on the standard server just to clarify.

I ran some maps and finished some towers.
After finishing the tower and attempting to put tablets in the towers to influence, nothing happens.

Not sure if this has something to do with the number of nodes available to influence, but I tried putting a single tablet even with 3 unlocked, I can't seem to influence the other nodes.

Thanks in advance for any input or help on this!
