Hi everyone,
I encountered a strange issue while working on a theme in Themler. After saving and closing my project, when I reopened it later some blocks that were previously hidden for mobile suddenly appeared again and were duplicated in the layout, even though they were still marked as hidden in the settings.
Because of this, the exported theme for WordPress shows repeated sections on mobile view while desktop looks normal. Has anyone experienced hidden blocks reappearing or duplicating like this after reopening a project?
