Input Script – Why do some P2SH spend transactions have data in both the ScriptSig and Witness fields?

I wonder if my wallet is broken or if I lack understanding of Bitcoin.

Here is the tx output consumed:

"value": 0.00180675,
            "n": 154,
            "scriptPubKey": {
                "asm": "OP_HASH160 771962306e72e479245d48e879dd2a1862225b4c OP_EQUAL",

Expense inputs are as follows:
