The transaction on 11 April 2022 for a Good Class Bungalow in District 11 was for a property less than 15,070 sqft, but it is still classified as a GCB.

You are correct—there are Good Class Bungalows (GCBs) in District 11 that have transacted with land sizes below 15,070 sqft (1,400 sqm), including the April 2022 transaction you mentioned. These cases generally occur when the GCB was approved and built before the current URA guidelines were implemented. Such properties are considered "grandfathered" and retain their GCB status even if their land size falls below the present minimum requirement.

For new GCB developments or redevelopments, the current minimum land size of 1,400 sqm applies. However, existing GCBs that were already approved before the rule change are exempt from this requirement and can be legally bought and sold as GCBs in official records. District 11 is one of the areas where these exceptions are sometimes observed.
