Hello,

currently we have an issue (after upgrading ignition to 8.1.36 from 8.1.31) where all Custom tag properties set to DATASET have been changed to STRING after update. We have to set them back manually, BUT every GW restart or an import attempt ends with the same issue.

we are a bit desperate, because we are using DATASET custom props of TAG a LOT.

please help
