Tracktion Waveform Pro 12.5.5: Issues with hitting [Tab] and [Enter]

[aptitude42Trends]

System details:
OS: Win10
Program: Tracktion Waveform Pro 12.5.5 (Build 31)

Issue #1:
Procedure: After clicking on the "Volume & Pan Plugin", input a numeric value using the keyboard into Volume field, then hitting tab, it takes me to the Alias field.
Expected behavior: As per the previous versions of Waveform Pro 12 (12.1/12.0) Waveform Pro 11 and Waveform 11 Free, hitting tab would take me to panning.
Current workaround: Click on panning.

Issue #2
Procedure: After clicking on the "Volume & Pan Plugin", input a numeric value using the keyboard into Pan field, then hitting [Enter] on either the numeric or alphanumeric section of the keyboard, I press the [space bar] and nothing happens.
Expected behavior: As per the previous versions of Waveform Pro 12 (12.1/12.0) Waveform Pro 11 and Waveform 11 Free, hitting the [Space Bar] would trigger Play.
Current workaround: Click anywhere outside of this field and hit [space bar].

Given this, what are my options? Is there anything I can do to resolve this or is this something that needs intervention?
