Ruleflow conditions does not show the condition operation on the condition's dropdown menu

While editing a business process the ruleflow based on conditions seems not to work properly with the kogito-tooling.

Current Behaviour:
When a rule flow is selected and a Process Variable selected as well, the conditions do test the variable are not shown, see attached screen-shots.

Question:
at least for basic comparison like eq, lt, gt booleans wouldn't be better to have the stunner handling it and let the kogito-runtimes parse the process accordingly?
