When using 2D scan sweep_2 variable value prints to 0.0 in terminal irrelevant of actual value

[kj5248]

Describe the bug

When using 2D scan the value for the second variable is printed as 0.0, for example:

Starting scan point 1:  Aspect_ratio, aspect = 3.0 and Net_electric_power_(MW), pnetelin = 0.0 

This only happens for the initial point, if you use multiple points for nsweep_2 the value that returns 0.0 is the first value in the list rather than the first scan point. Note this does not impact the actual value which is used correctly and outputs without issue.

Steps to reproduce

Run 2D scan using scan_dim = 2, and any variable for nsweep = 1 and nsweep = 2. For example used:

scan_dim = 2
* DESCRIPTION:   Number of dimensions for variable scan
* JUSTIFICATION: 1-D or 2-D scan switch (1=1D, 2=2D)

nsweep = 1
* DESCRIPTION:   aspect ratio

nsweep_2 = 3
* DESCRIPTION:   pnetelin

isweep = 1

isweep_2 = 1

sweep = 3.0
sweep_2 = 400
