Fire spreading on nether portals does not work

Hi. I have problem with „ fire spreading” on nether portals. (It doesn’t work).

I made a world on last version before the new update and made a realm of it ( I updated the game on Tuesday so it’s on newest version now). I started building gold farm yesterday and first portal worked( was lightning up and breaking on its own as is should) and today I made second portal and it worked too, then I taked the water that was laying on portal after I switch the system off, and I put it to dispenser back. And from that moment every single portal already build and older was not lightning up from lava on its own. ( I didn’t do anything else) To be clear, I want to write every thing that happend before to give u some clue what’s going on but the main problem is fire spreading on portals that does not work. ( I dropped there 3 videos what is like)

When I was building next portals some would light up once and after that they stop lightning up. I build simple example on the side on copy world and it was the same problem.

On copy on my old word from a year ago when I have the same farm, everything is still working so I do not know what happend. In a few seconds fire spreading stopped working ONLY on portals . I tried to break and place again lava or trapdoors or left the portal with no water in to light up but nothing helped. I mean it is weird.

I made the copy of realm and it didn’t work on copy too. I didn’t tried it on new world tho…

Reloading the world didn’t worked.

First video two video is copy of the realm, the world that I have problem on. And third video is copy of my old world.

Thank You for your time
