Strange column overwrite issue with an action on other columns.

[shimodabt]

I think I have isolated a strange issue, but I don't understand how to fix it. 

This action updates the value in 2 columns but seems to empty the value in another column. 

Note:

• No bots are involved in modifying these columns and all bots on all tables have been stopped to isolate this issue. 
• I have regenerate the schema for Adresse
• There is no Formula or others for Obligation DateTime

Any idea would be appreciated.
