The issue is that when you remove a heading, text block, section from a page that has been build by Bricks, those old, removed, elements still show up in the WPML Advanced Translator tool. This is the case for their old and new version of the translator tool.
The only work-around I found is duplicating a page and afterwards remove the old page. This results in the Advanced Translation tool showing only the strings that are there on the page.
Hi,
thank you for your report. As you already mentioned, we have an internal task for this in our local bug tracker.
