We upgraded our migration chain last week from FME 2025.0.1 to FME 2025.0.2 and our Excel writers started to mess up xlsx files. Some column names are renamed and hundreds of them added all with the same name: "Created by LibXL trial version 4.5.0. Please buy the LibXL full version for removing this message."

Strange thing is that not all workbenches are messing xlsx files like in the screenshot. Some of them behave as before in FME 2025.0.1. I indeed find libxl.dll library in the plugins folder of FME installation and version is 4.5.0.0.
During upgrade to FME 2025.0.2 all workbenches, transformers, readers and writes are upgraded. Recreating Excel writer in FME 2025.0.2 does not help.
Can someone please give me a hint if its possible to overcome this issue in FME 2025.0.2?
