Hello Martin, please take a look at the doc changes for Fuse integration and the release note for the same "Known issue". Because this version discrepancy is a bit of a "one off", we would like your SD sign off before releasing this information. Let me know if you have any questions regarding how we came up with this solution. Thank you.
