When duplicating an SP Page Builder module and inserting both modules into a page via the “Joomla Module” addon, both end up showing the same background image and the same font, even though each module is configured differently.

Environment: Joomla: 5.x SP Page Builder: 5.x (Pro) Template: Helix Ultimate 3.x PHP: 8.x Browser: Chrome 139 Caches: Joomla / Helix / SPPB cleared multiple times SPPB vPro.5.7.2

Steps to reproduce: 1.- Create an SP Page Builder module. 2.- Add a Heading and a Text Block. In Text Block, set Local fonts (e.g., Open Sans). 3.- In the module section, set a background image. Save. 4.- Duplicate that module. 5.- In the duplicated module, change the font (different typeface) and change the background image. Save. 6.- Create a page and add two sections with the “Joomla Module” addon. 7.- In each section, select one of the two modules (original vs duplicated).

Expected result Each module keeps its own background image and its own font.

Actual result Both modules display the same background image and font (one module’s styling seems to override the other).

Hypothesis Looks like a CSS / unique ID collision on duplicated modules, so the generated CSS for one module overrides the other when both are loaded via “Joomla Module” on the same page.

**** Until the bug is fixed, avoid duplicating: create each module from scratch and re-enter the content.
