Versions InDesign 2024, InCopy 2024, InCopy 2022, InDesign 2022
Steps to reproduce:
- Open InCopy
- Make a new document
- Insert a 4x4 table
- select table and set all strokes to zero width
- enter text in col2:row3, col2:row4, col4:row3, col4:row4
- make the bottom edge stroke of col2:row3 4 points thick and color black
- make the bottom edge stroke of col4:row3 4 points thick and color 100% cyan
- save and close the document
- open the document and observe strokes are intact
- merge col3:row4 with col4:row4
- set text in last cell of rows 3 and 4 to align right
- save and close document
- reopen document and observe the cyan line is missing

The attached video proves it in InCopy 2022, but the same happens in version 2024.

The CYAN stroke is also missing when the files are brought into InDesign.

The ICML shows the correct BottomEdgeStrokeColor and BottomEdgeStrokeWeight

The attached video shows the steps.
