RCA reusing FCC IDs for different products?

TL;DR - We noticed RCA reusing an FCC ID for 2 separate android tablet products. The FCC ID printed on their Intel design is from an ARM design. Images here - https://twitter.com/SiddharthKandan/status/811810300794171392 https://twitter.com/SiddharthKandan/status/811821993393786880

We bought an RCA Voyager tablet from Walmart - https://www.walmart.com/ip/RCA-Voyager-with-WiFi-7-Touchscreen-Tablet-PC-Featuring-Android-6.0-Marshmallow-Operating-System/53990885

The packaging stated it was an Intel tablet. We validated that it was an x86 processor that gives Intel device IDs as it's booting. The back of the tablet has "FCC ID: A2HRCT6773W22" printed. FCC site - https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Sum&calledFromFrame=N&RequestTimeout=500&application_id=me2wM0wUnE%2FY60iY7Gk1qA%3D%3D&fcc_id=A2HRCT6773W22

FCC Document Details - https://fccid.io/A2HRCT6773W22 The documents on the FCC website state it's supposed to be a Mediatek ARM tablet and not an Intel Atom. Our best guess is that they didn't want to pay for certification again. We also considered that Walmart may check FCC ID during product certification and this change may have gone unnoticed when fulfilling orders to Walmart. Is this common? Any other guesses to motivation?
