Checklists Becoming Corrupted When Rapidly Completing Items

[GTHub23]

Checklist

• I made sure that there are no existing issues - open or closed - to which I could contribute my information.
• I made sure that there are no existing discussions - open or closed - to which I could contribute my information.
• I have read the FAQs inside the app (Menu -> About -> FAQs) and my problem isn't listed.

Affected app version

1.1.0

Affected Android/Custom ROM version

Android 13

Affected device model

Moto G82

How did you install the app?

Google Play Store

Steps to reproduce the bug

1. Create (or use) a current Checklist
2. Create at least 2 items in checklist; I used "Test 1", "Test 2", "Test 3"
3. Tap 3 Dots > "Export as file" and "Update the file itself..."
4. 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

In the event the files I uploaded are unreadable, please find below a copy of the code from these files if required:

Just tried to replicate this issue again whilst doing a screencap but it didn't happen every time. However, I did eventually manage to capture a short video of the glitch occurring

Please find attached a screencap in MP4 format. I accidentally tapped the resulting individual checklist item which checked it as done; normally this would remain unchecked once the glitch occurs
