It has nothing to do with the Super Bowl. As I said in my reply, on January 29th they initially announced "Springland" as the 2nd episode airing on 2/18, then a week later on 2/8 they revised their schedule and bumped up "Missoula" (which was originally going to air as the 4th episode on 3/3) to 2/18 and pushed "Springland" to 2/25 and "Mt. Shasta" (which was originally going to air on 2/25) to 3/3
The on set publicity photos also show that Missoula was filmed a month after Springland and Mt Shasta, so either the episodes were filmed out of order or CBS is airing it out of order
Gracenote has since corrected the numbering to reflect CBS's airing order so EP045807170004 "Missoula" is now listed as S1E2, EP045807170002 "Springland" is now listed as S1E3, and EP045807170003 "Mt. Shasta" is now listed as S1E4, but I'm not sure if Channels will automatically update the metadata of existing recordings next time you refresh the guide data.
Also, Gracenote's guide data powers a lot more than just Channels DVR. The episode numbering issue also affected DIRECTV, Optimum, Cox, Xfinity, Verizon FiOS, most ex-TWC/Brighthouse Spectrum systems, Bell TV up in Canada where the show is simsubbed by CTV, along with Silicondust/HDHomeRun and anything using Schedules Direct.
