Retain variable after update/download datablock

ev200

Hi, is there some way to retain variable from datablock after updating the same datablock in s7-1200?
im using s7-1214c TIA Portal 11 SP2 and v12 whitout any luck, after updating datablock lets say with new variables, old variable marked as "Retain" gets set to zero
in the manual it says

"When you download one or more DBs from STEP 7 V11 to an S7-1200 V2 CPU, the
retentive and non-retentive values of those DBs are set to their start values. The next
transition to RUN performs a warm restart, setting all non-retentive data to their start values
and setting all retentive data to their retained values.

When you download project elements (such as device configuration, code blocks or DBs)
from STEP 7 V10.5 to any S7-1200 CPU or from STEP 7 V11 to an S7-1200 V1 CPU (or a
V2 CPU that has been configured as a V1 CPU), the next transition to RUN mode resets all
of the DBs in the project to their start values."

so im using STEP 7 V11 SP2 and S7-1200 V3 and still my retentive values get resets
what im doing wrong?
it was so easy on s7-200 to use retentive variables...

Thanks
