Steps to reproduce the bug

Create (or use) a current Checklist
Create at least 2 items in checklist; I used "Test 1", "Test 2", "Test 3"
Tap 3 Dots > "Export as file" and "Update the file itself..."
Quickly check 2 items in rapid succession

Expected behavior

Items in checklist should become checked/scored out/ticked and be displayed normally

Actual behavior

All items are condensed into 1 item which shows the files underlying code for the checklist, and cannot be mannually separated

A new file must be manually created within the app to replace the old file, and all previous entries manually entered again

Screenshots/Screen recordings

Please find attached a copy of the Test Note I used in TXT format which is in working order: @Checklist Test Note Working.txt

And a copy of the Test Note I used in TXT format which is in broken: @Checklist Test Note Broken.txt

Additional information

I have attempted to try and replicate this bug by using a note stored only within the app, and have been unable to replicate it; that is to say I skipped Step 3 of "Steps To Reproduce..." and immediately attempted Step 4
