No, it wasn't. It has been correctly tagged as highway=cycleway since it was first mapped in June 2011. I added the segregated=yes tag in October 2018. A StreetComplete user surveyed it in June 2021 and added the tags for the different surfaces.

You've added the access tag bicycle=designated and changed foot=yes -> designated. That isn't incorrect, but it doesn't correct any mapping error, real or imagined. The effect of this edit on OSM-based routing software is nil, but it's harmless.
