World Ready Paragraph Composer Causing Squashed Last Line with Footnotes

I have a potential solution for you - but it might induce reflow throughout your document. I downloaded your test doc, but was unable to find the KFGQPC font. Fortunately, that doesn’t matter for our analysis, as the “my friends” line with the composition problem has no Arabic in it.  

I looked at the Document History as Mike suggested, and found that your file was started in version 20.4, and was updated to version 21.1 in September of last year. I think that such file updating works for many users, but I usually work in complex scripts (like Arabic or Burmese) and have found that the text composition engine can change significantly between versions, and those changes can result in weird text flow issues. Furthermore, if you have a frame that you created and filled with text in version 20.4 and then open that file in 21.1, and do not edit the frame, then the frame will continue to render according to 20.4 rules, until you make changes to the frame, at which point it will re-render, sometimes with errors. 

My global suggestion for you - for all users of non-Latin scripts in InDesign - is to never update your document by simply taking your old INDD and opening it in the latest version of InDesign. You are much better off either a) continuing to work in one version of InDesign, no matter how many years you continue to use the same document, or b) exporting IDML from your old version of InDesign, opening that with the new version, with the expectation that you’re going to have to proof the entire document due to the likelihood of text reflow due to changes in the underlying text composition engine. 

What I did to resolve your compressed “my friends” issue was this: I made a single change to the paragraph. That caused the paragraph to re-render with the text composition engine in 21.2. All I did was add a space to the paragraph, which causes the entire story to change how it is composed:

Since you have already clearly been working on this 20.4 file in 21.1 for a while, I would suggest that you make some updates. Firstly, update your InDesign 2026 to the latest version (21.3, I believe) right away. (Also update your 2025 install to 20.5.2, while you’re at it.) There were quite a few bugs in 21.0 and 21.1 that you wil want to avoid. After that update, you should force the text to recompose with the Recompose All Stories command (Command+Option+/) to force all stories in your document to redraw. This will lead to text flow changes throughout your document. You might also consider exporting to IDML and reimporting, which should force your stories to be recomposed according to 21.3 rules, and also clear out other potential document corruption.

I recently learned there can be differences when the document was create in an ME version versus western version, somewhere deeper than the typical ME settings. Haven’t yet further investigated, but when there are differences I’d first ask for a copy of the .indd itself.
