For anyone having this problem.
1) What is the name of the repeater field
2) What are the names of the taxonomies on your site
3) does your repeater field name match any of the taxonomy slugs?
4) If this is happening on an options page, does the field name match "options_{$taxonomy_slug}"
It could be possible that if you answer yes to 3 or 4 that ACF is somehow mistaking your repeater fields for termmeta fields, but I haven’t dug through the ACF code enough to tell.
