content labelled multiple times

Error message

content labelled multiple times

What it means

Warning in eval_markup: a label expression attaches to preceding content, but the nearest labellable element already has a label, so the new label would overwrite (or duplicate) an existing one. Multiple labels on the same element are not meaningful.

Solutions

1. Remove the duplicate label
2. Move one of the labels so each labels a distinct element
3. Wrap the element in another container if both labels are genuinely needed
