stackStripMap.py run_04 'e vector 2 error'

[keepfighting666]

I am using ALOA1.0 data and following the process of generating interferograms with stackStripMap.py. When running run_04_refineSecondaryTiming, I encountered these messages. I'm not sure if they will affect the subsequent processing or if they can be safely ignored.
I would greatly appreciate any guidance on how to resolve this issue.
1)
WARNING - number of samples availabe for estating gross offset is NOT power of 2: 80
the value is computed as 2*i_srchy/winsize_filt
better to make it power of 2 for FFT
current i_srchy (azimuth search window size): 40
current winsize_filt (azimuth filtering window size): 1

2)
e vector 2 error

3)
Bad match at level 1

from this question:#855.
3) can be ignored?
