misbehaving nether portals

MCPE BETA 1.19.0.26

i had a nether portal built near my base. i have built another portal in an ancientcity which is 2000 blocks away from the portal near my base. i have lit the portal(the one built in ancient city) and tried getting teleported to the nether. i did get teleported to nether but i got out of the portal connected to the one built at my base. i tried going back to back to the ancientcity through that portal. i ended up teleporting to my base. i had to go all the way to the ancient city again. please fix this bug asap.
