(Get the code!)
CtC,
For now, if you are able, I suggest selecting the LAST option in the kernels list, on Cubic's Kernels tab. For Ubuntu 19.10, this is kernel 5.3.0-18 that is used to boot the original ISO from Canonical.
Please keep in mind, that the kernel used by your customized OS, once it is installed to a computer, will (usually) be the latest kernel that you had installed in the chroot environment. The purpose of the Kernels tab in Cubic is to select the kernel used to bootstrap the Linux OS from the ISO/USB. (Your computer needs to know how to read an OS from the ISO, and this is what bootsrtapping does).
Usually, it is best to select the kernel that Canonical has packages on the original ISO. However, one drawback is that, when you are in the Live environment of the customized ISO, it runs the kernel you had booted your ISO with; this is only for the Live environment, and not for the final installed system.
I do see an issue in the Kernels tab of Cubic, where way too many kernels are listed. However, even after this is fixed, please bear in mind, it is possible your customized ISO may not boot with an ISO boot kernel different from the one supplied by Canoncial (the official bootstrap kernel, last in the kernels list).
