There is no workaround on client side, the issue should be fixed on BE ('location' property is lost after 'clean up' function execution). Moved to milestone 'Release 2.6'

When calling the CleanUp function, we send such data
"mol1": { "type": "molecule" "atoms": [ { "type" : "rg-label", "location": [1.3, 6.9250000001, 0], "$refs": ["rg-3"] } ] }
, while we receive the following as a response
"mol1": { "type": "molecule" "atoms": [ { "type" : "rg-label", "$refs": ["rg-3"] } ] }
, that is, there is no "location" field
