No graphs after migrating HMC connection from SSH to REST API

LPAR2RRD 7.40

vHMC V9R2 Service Pack 952 with all iFix

Power Server model 9008-22L

Something strange happens to me, after migrating the connection with HMC from SSH to REST API, one of the POWER servers has allowed graphs to be show only in the "Total" and "Total Max" tabs of the CPU section, the rest of the tabs refresh and show correctly the info.

Is there a way to force refresh only those tabs?

The REST API connection test on this POWER server gives OK

Any suggestion is welcome.

Thanks and regards,
