problem on step 3

when i start to import, for step 3 page, all tab including
title % content
images
wp job manager field editor resumes add-on
custom field
other resume options
function editor

can NOT be opened

so nothing to do on step three, it import nothing on finally stage(because most of the field is custom field(using “wp job manager custom field” to make it)

i using wp all import pro,wp job manager custom field,wp job manager resume,this plugin, wp 4.98 (all plugin is most update)

thanks
