I have a portal that functioned perfectly until I made a second one, now the first portal, as I leave the nether, drops me in bedrock (it works perfectly going from overworld to nether and the second pair works fine both to and from the nether)
portal coords: 5 11 -317
where it sends me: -14 1 -239

what I assume to be the relevant part from the log:
[13:48:23] [main/WARN]: Ambiguity between arguments [teleport, destination] and [teleport, targets] with inputs: [Player, 0123, @e, dd12be42-52a9-4a91-a8a1-11c01849e498]

I have a datapack installed but as I said it worked fine before even with the pack, I have also tried removing the datapack but it makes no difference

I have tried breaking and then relighting both the overworld and the nether portal but it makes no difference
