SCCP Extension dropping first digit (BUG?)

Discovered, that inbound calls (Zap based in my example) punching an internal extension at an IVR prompt can dial SIP extensions with the full 3-digit extension (e.g. 111) … however SCCP extensions can only be reached by dialing the last two digits (e.g. 19 for ext 119, somehow it duplicates or assumes the initial “1” I am guessing)?

Running a pretty lightweight/clean FreePBX config. Any idea if this is a FreePBX dialplan bug for Custom extensions?

Thanks all,
