Did I fuck up?

So I managed to change the CSC of my s24U to INS (India) since I moved back to India from the UK. The log here weirdly shows up as INS/EXU. Does this mean I screwed up while I changed the CSC or do I have both the CSC's installed? Wanted to ask this because I read somewhere that this fucks up OTA updates for the phone and it's come to my attention that the Feb security update was out today in India but it hasn't shown up on my phone. Please help!
