Describe the bug

When reading a frequency off a P2P Tunnel block if you read off the block you added as a destination it creates a new frequency.

How to reproduce the bug

1. Create a new P2P unlinked tunnel, we'll call the P2P blocks P2P Tunnel A and P2P Tunnel B
2. With a memory card in hand, duck click on P2P Tunnel A to assign a new frequency to the card and P2P Tunnel A
3. Right click on P2P Tunnel B to apply the frequency to P2P Tunnel B establishing the tunnel, working as expected so far
4. Clear the card by ducking and right clicking away from devices
5. Read the tunnel info from P2P Tunnel A by ducking and right clicking it, works as expected
6. Clear the card by ducking and right clicking away from devices
7. Read the tunnel info from P2P Tunnel B by ducking and right clicking it and notice that a new frequency is assigned even though we should be reading the frequency off that block

Expected behavior

I should be able to read the tunnel frequency off any end of the tunnel?

I ran into that as well in here: #7524

Basically it is "works as designed" where the actual design is not that intuitive. For now just keep copying from the source (i.e. your Tunnel A). This might result in a trip back to the controller every time.

As far as I remember the maintainer indicated at some point that a general overhaul of the P2P frequency system was on some sort of list for improvements in a future release, without specifying a time frame.
