Likely similar to #1605 (comment)

[yaacovCR]

Fix might be along line of #1614

[falkenhawk]

But #1614 was already released with v6.0.9 🤔
edit: Ah nvm, different files were modified in that PR. Now we need a similar fix in WrapFields

[yaacovCR]

See #1783

Let me know how it works for you...

Released in 6.0.14.
