Issue with writing to SDE feature class and archiving enabled

Hi FME and ESRI users,

In an SDE feature class archiving is turned on.

When writing a record in update mode, an attribute is blanked out, all other attributes get values.

But redirecting to the Data Inspector shows a value for the attribute.

We checked the data type in SDE and FME and they match.

Any idea what could be causing this issue?

Your suggestions are highly appreciated.
