Incorrect Shey Usage, Missing Spaces, UI Contrast Issue, and OCR Error

[losangden]

Thank you for addressing the bugs I reported — much appreciated!

Here are a few more issues I’ve noticed:

1. The app is incorrectly adding the 'shey' character (།) at the end of every line, even when it's not appropriate. It should only appear where grammatically necessary. I've highlighted these cases with orange lines.

2. Additionally, the app is missing spaces where they should be inserted — these areas are marked with green lines.

3. The options "Export all as single file" and "Insert page number before each page" are not readable due to black text on a black background.

4. On PC, we’re getting the following error:
   “Failed to run OCR on selected image. Input image is None.”

However, the same file works fine on Mac.
