Could you fill that metafield up with some spaces? basically just and hit save? or you could also type
This creates a blank space.
Maybe the way you setup the code is when the metafield is not filled up, it just shows 0.
Topic summary
Problem: On one collection page using the Studio theme, a “0” appeared under product names.
Context: Other products display size text (e.g., 32 x 32 Canvas) via a product metafield; the digital products in that collection had that metafield empty. Metafields are custom fields used to show extra product information.
Cause suspected: The theme’s code renders 0 when the metafield is blank.
Suggested workaround: Populate the metafield with spaces or a blank character to suppress the 0.
Outcome: The merchant instead filled the metafield with size values like other products; the 0 disappeared and the sizes now support filtering.
Status: Resolved. No further action requested, though empty metafields may still show 0 unless the template logic is adjusted to hide empty values.
