Hi,
thank you. I was able to replicate the issue locally and I’ve added it to the bug tracker. As a workaround, this should work {echo:get_field('acf_field_id')}, just replace acf_field_id with the name of your field.
If you want to fetch from options, use this: {echo:get_field('acf_field_id','options')} . Also, don’t forget to allow get_field function to run.
You can read more about it here: ACF | get_field()
Thanks,
Matej
