How to disable number recognition in Inserted OLE objects?

[laz442]

LO 6.2.7.1

Inserted LO Calc object in Writer document.

Cannot figure out how to turn of %$#"%#$" number recognition.
Have formatted cells as numbers, and I still get Date recognition.

Have googled, but only see results for full Calc documents.
I have everything in Tools → autocorrect as OFF

%$#"%#$" doesn’t look like a valid format string

What do you type? What do you expect? What is the result?
