Missing parts from back of cards

[summer osprey]

Some cards have missing parts at the back. This is only on AnkiWeb, the cards are completely normal on my computer. I’ve tried editing the cards and then resyncing to see if that might help, but it hasn’t.

It's hard to tell you much when we don't know what these are supposed to look like. (Screenshots of what these cards look like when they are correct would help.) But let's suppose it's formatting related to start with -- like white text on white background.

There are 3 Styling and formatting places that color can be coming from.

1. The styling for your note type, where classes of formatting can be defined overall for all of the cards, or for specific cards, or specific parts of cards.
2. The card templates themselves call those classes defined in styling, but they can also contain formatting for specific field replacements.
3. Formatting in the text of a specific note is controlled in the note editor by the editing toolbar. If there's a lot of that to remove, Find and Replace might be useful. You might need to open the HTML view (click < > above the field) to see it in the field.

Since this looks like it might be only parts of a field that are being impacted, #3 seems the most likely, so start there.
