Connection using custom variable not working.

When arriving at a given interaction, I am able to showVar for a previously set custom variable.

So this confirms the variable is set.

But at this same interaction, I try to set conditional connections with the conditions:

If custom variable contains whole word then go to .

But it never works. No action happens, not even the fallback connection.

What could be the problem? There is no user input at this time. I want the bot message to be shown and then for it to evaluate a previously set variable to decide which reponse/interaction to go to, without user input at this stage.
