LattePanda Delta stuck in logo

Hi, I have this problem with several latte pandas delta that I am using in a project, In those, I installed ubuntu 18, and I installed the auto-power-on after power failure feature (https://www.lattepanda.com/forum/topic/314325), but in many cases when I reboot the latte panda or cut the power of the lattes they get stuck in the yellow logo of latte panda, or in a black screen, so I manually need to cut the power supply many times in order to latte init well, I Tried with ubuntu 16 and that same thing happens, and I tried with USB-C power adaptor, and board power pins and the same thing happens some times in all boards
