Tank lvl6 DC not working as described

The lvl6 tank DV in the new set is not working correctly. It says tanks should recover protection after losing it the first time. But I had a battle against Finn, Holdo, and Zorii where Finn and Holdo recovered it every time it was lost. I think my Gar Saxon was similarly affected by my own lvl6 tank DC, but wasn’t watching for it as closely. I have a recording of the battle but can’t upload it because the file is too large.
