@GJ , I have seen this behavior reported by other customers in the past when they are using invalid tags, such as having a space in the tag name. Can you please check to see if this is the issue?
A tag can be any string, up to 120 characters, containing alphanumeric and the following non-alphanumeric characters: '_', '@', '#', '.', ':', '-'. Note that spaces are not supported.
Please let us know if this resolves the matter or if you still need assistance.
