Ansys Workbench Transient Thermal, Problems with Single Frame Restart and Ekill

Hello everybody,

I have some problems with a simulation of an additive manufacturing process in Ansys Workbench thermal transient.
The multiframe restart is not provided in transient thermal (not supported), so the only option is the single frame restart, which unfortunately causes some problems. I need the restart to create Surface 152 elements for further thermal loads on the current surface of the extruded material, for this a trip into the preprocessor /prep7 would be necessary within the solution /solu.

In the simulation, a body (path) is initially deleted with ekill and then a defined volume is successively generated step by step using ealive (see results without restart videos). This works very well (the bottom picture on the right). Without Restart.
With the restart, the element deletion and generation no longer works as planned (see the bottom picture on the left).

The code of the two APDL snippets I use looks like this:
Command object 1 ("initial_ekill) for the element deletion of the volume to be generated:
Code:
________________________________________
nropt,full
/prep7
cmsel,s,path
ekill,all
finish
/solu

Command object 2 ("AM_process") for the element seletion of the volume to be generated and generation of the printed path:

Code:

I think the problems are related to the database for the restart.
I must somehow initially delete the elements of the volumes to be created without causing problems with the database for the restart.
PS: Unfortunately the upload of video files does not work, otherwise I would have attached videos for illustration.

Best regards
