Theme global settings reset to default after Publish and refresh

Hello there,

There is an issue when trying to change the Qubely Global Settings.
I am activating the Theme global settings, then Publish the page.
At first, everything seems fine, the colors are updated however if I refresh the page editor, the Global Settings are set back to the default plugin settings – Preset #1 and if I Publish again, the old colors are applied front-end as well.

Can you pls. help me with this issue to be resolved?
Thank you!
