When you have more than one channel available, every channels shows in only one line :

Issue persists on MC1.20.1 AE-Additions 5.0.5 ATM9 (Running Server Side)

Unable to create new channels, however even though no channels are showing, existing transceivers are still connected.

Really looking forward to the fix of this thing. And possible improvements to this block.

Youre also incapable of deleting the channels, making the block outright unusable unfortunately

Thanks for reporting this. I'll take a look at this sometime today

Block stops working after spamming "Acess mode" and/or spam create new networks... Is there any way to delete those 'ghost' channels without the block GUI?

Is there any update on this? I’m also running into this issue on ATM9 and it’s unfortunately preventing me from some AE2 expansion.

I compared the codes of 1.19.2 and 1.20.1 and found the following errors:
MEWirelessTransceiverScreen.kt
channels.forEachIndexed { index, channelInfo ->
val channelField = this.channelFields[channelInfo]
if (channelField != null) {
channelField.updateValues(shouldShowChannel(index), selectedChannel == channelInfo, channelY)
channelField.render(guiGraphics, 0, 0, 0f)
}
}
==>
channels.forEachIndexed { index, channelInfo ->
val channelField = this.channelFields[channelInfo]
if (channelField != null) {
channelField.updateValues(shouldShowChannel(index), selectedChannel == channelInfo, channelY)
channelField.render(guiGraphics, 0, 0, 0f)
channelY += 12
}
}

Issue with channellist and not able to delete channels still persisting.
"Workaround" I found is that if you create a channel and save it, you select the last made channel. Have been able to link up the transmitters like that until it's fixed.

Same issue on ATM8 last version
