How to Remove/Address the Blue Triangle:
1. Resize the Text Box:
Drag the handles of the text box to make it larger, revealing the hidden text and removing the triangle.
2. Adjust Font Size:
Reduce the font size of the text within the box, allowing more text to fit within the current dimensions.
3. Link Text Boxes:
If you're using linked text boxes, ensure the connection is correct and that the overflow is routed to the next box in the chain.
4. Delete Empty Paragraphs:
Sometimes, extra empty paragraphs (marked by ¶) at the end of the text can cause the triangle. Deleting these can resolve the issue.
