I am designing an audio amplifier for which I need a class AB output stage, I am in need of TIP 31C and TIP 32 C, I pasted the model into the
LT spice Lib in standard.bjt , but when simulated, it gave the following error, a screenshot is also attached. Help me out with this error:

Unknown model type "npn+is" -- ignored
Unknown model type "pnp+is" -- ignored
Direct Newton iteration for .op point succeeded.

Open the ill-fated standard file. Find in it "npn+is"
Do the same with a string that has "pnp+is".
And you can just replace + with a space in these two places!
npn+is ==> npn is
pnp+is ==> pnp is
