SIMPL+ NVRAM allocation was introduced in CCD Disp Eth v1.14.
(F1 Revision History calls out "Added ability to page through more than 10 user attributes.")
SIMPL compiler calls out max NVRAM allocation for the program slot after adding 20-something CCD Disp Eth instances.
For now the workaround is to use CCD Disp Eth v1.13 or split the CCD Disp Eth v1.19 module instances into multiple program slots.
The Driver team is working to utilize SIMPL# (instead of SIMPL+) for holding the persistent data to correct this behavior.
I don't have an ETA for the module update that will accomplish this, but it is something we're tracking, and I'll update the thread when I know more.
