Labels in layouts exported from ArcGIS Pro 3.5.2 and 3.6 as default Adobe Illustrator Exchange (AIX) file are split into separate elements on curved features when viewed in Adobe Illustrator 29.6.1, using extension ArcGIS Maps for Creative Cloud Plugin 3.9.

Workaround

• Manually group the split label elements in Adobe Illustrator.  
• Convert labels to annotations within ArcGIS Pro prior to exporting. This approach helps preserve label integrity and grouping in the resulting AIX file, minimizing post-processing efforts in Illustrator. 
• Use ArcGIS Pro version 3.5.1 for exporting layouts. This version does not exhibit the label-splitting issue, and both curved and linear labels are retained as grouped elements, allowing for seamless editing in Illustrator.
