richTextField function was working partially

Hi 

In Interface under columns layout richTextFied was defined so that field was displaying to us and whatever the test user which i created newly same like user access for that also it was displaying that field but to the users it was not displaying there was no visibility conditions defined, when i replace that richtextField with paragraph field by passing same parameters then users were able to see that paragraph field so could you please confirm what exactly might be reason for this weird behavior 

 a!columnLayout(
            contents: {
              richTextField(
                label:ri!resourceBundleDict.Signature,
            
                labelPosition: "ABOVE",
                richTextValue: local!maintenaceCDT.sign,
                richTextSaveInto : local!maintenaceCDT.sign,
                enableProgressBar :false()
              ),
              /*a!paragraphField(*/
                /*label:ri!resourceBundleDict.Signature,*/
                /*value:local!maintenaceCDT.sign,*/
                /*saveInto: local!maintenaceCDT.sign,*/
              /*)*/
            }
          )
