KNIME - Overwrite Cell with Formula in Excel

Hi. I’m new with KNIME and I’m having issues on the write-to-excel template node.

In my excel template, there is one cell with existing formula.

My workflow should have updated that cell but when executing the node, all other cells were updated except for that one cell with formula.

Below sample I made to show you:

Upon reading some discussions, I tried replacing them first with missing values, but still the same happened.

Is there any way to solve this? Thank you.
