[TYPO3] Insert Records in Normal column issue

[Tim Boesenkool]

Hey List

I'm working on a v3.8 site that has a problem with inserting records in the
Normal Column.
I can get insert records to display in left/right/border columns. But insert
records won't display in the FE Normal column. This seems to work fine for
everything else, except insert records.
I suspect it has to do with the following. Any suggestgions how this can be
tweaked?

marks {
content < styles.content.get
content_normal < styles.content.get
content_left < styles.content.getLeft
content_right < styles.content.getRight
}

Regards
Tim
