This has been a bug for a very long time. Cycling Heart Rate Lactate Threshold is often displayed on the Running Lactate Threshold Report for Current, 4w 12 and 1y. It makes it very difficult to see your running progression over time by displaying incorrect data. This occurs for both in the IOS App, Android, and on the Web UI. It looks like the API call provides the wrong data since it occurs on all platforms. It would be really nice if Garmin would fix this long-standing (Yearssssss longgggggg) bug.
