Unexpected Template/Schema IDs in Binance SBE Testnet Stream

Hey!
I connected to sbe testnet using wss://stream-sbe.testnet.binance.vision/stream?streams=btcusdt@depth/ethusdt@depth and i receive binary messages , however they have unexpected Template Id , schema id and version … Message Header received from testnet:
Template ID: 10003
Schema ID: 1
Version: 0 while expectation is : Message Header to be :
Template ID: 200
Schema ID: 2
Version: 1
Did anyone else face the same issue ?
Many thanks!

API and WebSocket Streams use different SBE schemas.

API responses spot_2_1.xml
Market data streams stream_1_0.xml
