From Mac to PC the text and slider is not consistent

I created a questionnaire using Psychopy builder on MacBookpro and then send it to a collaborator who is using a PC. I am not sure why but the version on the pc does not match with the one with the Mac. In particular, in this visual slider with the code below the triangle Insteon of pointing down, it is pointing left.

visual.Slider(win=win, name=‘VAS_LimbDef_PRE’,
startValue=None, size=(0.5, 0.1), pos=(0,0.01), units=None,
labels=labels, ticks=[1,10], granularity=0.0,
style=‘rating’, styleTweaks=(‘triangleMarker’,), opacity=None,
color=‘black’, fillColor=‘Red’, borderColor=‘black’, colorSpace=‘rgb’,
font=‘Open Sans’, labelHeight=0.04,
flip=False, depth=0, readOnly=False)

Also, in another visual slider which uses labels, one of the label (which is long) appears presented in two lines rather than one.

visual.Slider(win=win, name=‘VR_game_choices’,
startValue=6, size=(0.05, 0.3), pos=(0.3, -0.1), units=None,
labels=labels, ticks=(1,2,3,4,5,6), granularity=1,
style=‘radio’, styleTweaks=(), opacity=None,
color=‘Black’, fillColor=‘Blue’, borderColor=‘Black’, colorSpace=‘rgb’,
font=‘HelveticaBold’, labelHeight=0.04,
flip=False, depth=-1, readOnly=False)

How can I correct these errors? Do I need to have a specific set up/resolution for the display in both computers to have exactly the same presentation of the questionnaire?

Thank you
