Correlation replacements not applied to recorded script using auto-correlation

[dtschindler]

RegExp extractors are created but only a portion of those are applied in the script. Seeing many errors in the log stating:

ERROR c.b.j.c.c.a.ElementsModification: The source 'JSON' is not supported.Replacement's value 'y5vGmGtGq3Y5V0VFNdtybxK0V1wDXZZT7m5WCVaIg/k=' in the suggestion ReplacementSuggestion{replacementSuggestion=RegexCorrelationReplacement{, regex='', replacementString='', ignoreValue=false},...

• JMeter = 5.5
• Correlation Recorder = 2.0.3
• Plugin Manager (if applicable) = 1.9
• Protocol version (if apply, eg: Siebel CRM IP17 & IP18) = Mendix

To Reproduce

1. Create recording on a Mendix application using correlation recorder template in JMeter
2. Choose to auto-correlate everything found.
3. Observe that most regular expressions created do not get used in resulting script.
4. See error from above description

Expected behavior

No errors occur and correlations are applied to script.
