TIDM-1011: Missing Gerber file

Hi Team,

Here's an issue from the customer may need your help:

I downloaded TIDM-1101's Gerber file from TIDM-1011 reference design | TI.com, but I find this file missing the Groud Plane Layer when when I went into production. TIDM-1011 is a four-layer PCB board, the absence of Groud Plane Layer leads to the failure of normal production

Thanks & Regards
