Component stack mismatch error wile using Dynamic Repeating Layout | Pega 8.1.1

I have a requirement where i need to use Repeating Dynamic Layout (RDL) to display a section in List. During development, i am very well able to refer to the section of the Data class in the repeating layout, but at run time i am getting following error.

Section 'Perform' execution error on page 'pyWorkPage' of class 'AA-BB-CC-EE '. : Component stack mismatch {"pyCell":{"liveUI":"data-ui-meta=\"{'type':'Cell','subType':'pxDropdown','clipboardPath':'.RequestType','className':'AA-BB-CC-DD','pgRef':'.pySections(1).pySectionBody(1).pyTable.pyRows(1).pyCells(1)'}\"","pyLabelReserveSpace":"true","useLabel":"true","partialClass":"flex","automationId":"'2019020715304001878390-Label'","format":"pxDropdown","forLabel":".RequestType","pyAutoHTML":"true","pyGenerateUniqueIdForLabel":"false","spanClass":"iconRequired standard_iconRequired","cstmreqfor":"pyRequired","labelJSP":"false","pyLabelValue":"Request Type - Technical"},"pyName":"DynamicLayoutCell"}!!!!===={"scrollClass":"","centerInspectorData":"data-ui-meta=\"{'type':'Panel','subType':'CENTER'}\"","ariaLabelCenterPanel":"Center Panel","startWrapperDiv":"true","endWrapperDiv":"false","pyName":"pxWorkAreaContent","pyTemplates":[{"pxReferencedId":"f1d9f0e7b55568cc467ef833b061d4cc1a5145b2_6","pyName":"pxSection"}]}

I found a supporting article on PDN with a Hot Fix ID (HFix-48937):

https://community.pega.com/support/support-articles/component-stack-mismatch-error-post-pega-74-update

The given HotFix is only for pega 7.4 but the issue still exists in version 8 as well.

Any help regarding the solution is much appreciated.
