Bug Description
From https:/
If I add a voltage source with VALUE="AC 1 SIN(0 1 1k)" I get a 1kHz sine wave source in a Transient analysis. This is easy and handy if I know the nomenclature for a SPICE voltage source.
Then if I open the Spice Model Editor dialog I can see my 1V, 1kHz sine wave. Using the dialog I then change the frequency to "10k" and save. This adds a Spice_Model="ac 1 sin(0 1 10k)" property to the voltage source.
Now, the interesting part happens: the Spice_Model property wins and I get a 10kHz sine wave. But the old VALUE property looks like I should have a 1kHz sine wave. While it's understandable what's happening in hindsight, the UI certainly does look confusing.
There may be a way to force the parameters to be in sync or alert the user if the format of the VALUE field looks like a SPICE source and the parameters don't match the Spice_Model property value. Or some other resolution.

Here is the demo sallen_key filter circuit showing this behavior.
