Can't view CEL code in Flashpro

[02SilverSiHB]

UPDATE: I deleted the DTC, but for some reason flashpro never showed me the code. It hasn't come back in about 4 days straight now.

I've used flashpro before and never had issues seeing a code for a CEL. But I'm stumped on this one? Any idea what user error I'm making...have I forgotten how to see the code lol. I'm updated to the most recent update. If I check the DTC tab it's blank.

I go to check the CEL and it shows I have one on flashpro, but doesn't show the actual code.

I don't have the calibration (not unlocked to view) so I can't see if by chance the secondary sensor wasn't disabled, as I have the RV6 catted downpipe.

Car drives fine, but of course rev match is off when the code pops up. Comes back randomly, like every other day and only WOT at top of 4th.

Did you just installed your catted downpipe ?
go to DTC and try deleting P0420 and P0139 and retune it

No I've had my downpipe on for over a year.

I didn't tune it, the calibration is locked by the tuner.

Never had an issue like this before. And no it's not the tuner...he's tuned multiple cars I've mone before including the FL5.

It hasn't come back after a few days. No idea what the heck it was.
