Editor doesn't display images with 'at' transform properly

I have sprites with zoom transforms but they do not appear with transforms in the editor.

code:

transform tcommon(x=0, z=0.55):
    yanchor 1.0 subpixel True
    on show:
        parallel:
            zoom z*0.95 alpha 0.00
            xcenter x ypos 1680
            easein .25 ypos 1710 zoom z*1.00 alpha 1.00
        parallel:
            b2
        
    on replace:
        alpha 1.00
        zoom z*1.00
        parallel:
            easein .25 xcenter x 
        parallel:
            easein .15 ypos 1710
        parallel:
            b2

Please add the definition code of b2 and the using code "at tcommon."

i think b2 is irrelevant to the issue but i will post it here anyway:

transform b2:
    xzoom 1.05 yzoom 0.95
    linear 0.1 xzoom 0.95 yzoom 1.05
    linear 0.1 xzoom 1.0 yzoom 1.0
    yoffset 0
    easein .1 yoffset -5
    easeout .1 yoffset 0

line for tcommon:

show rg base2a eyes2a mouth2a at tcommon(960)
