While Controller not getting execute when use more than twice in Test Plan

Test Objective:Loop http sampler unless response contains a specified string "Success"

Problem Description:Using While controller and regular expression extractor to implement the test object but observed I can only use this logic only twice in my test plan.

When I use while controller with same logic 3rd time(for 3rd different sampler), it do not execute sampler even the condition is true and as a result my scripting is blocked, I cannot execute my test and really feeling low that JMeter doesn't support such simple functionality.

I am a JMeter user from last 10 yrs.

Please help here for immediate resolution.I have attached screenshot for the while controller block I am using.

While controller condition used is ${__javascript("${status}".indexOf("SUCCESS") == -1,)}
