Spectra buttons not following style book

We have an issue with the Spectra button block that isn’t affecting the core Gutenberg Button block. We also have the Front page from the Spectra “Horticulture” template installed but the below issue is site wide, not just the front page

When there is no style applied to the buttons in the Style book we have no issue and we can define each button as normal.

When we assign a style to the buttons in the style sheet things get weird. First, core Gutenberg buttons are unaffected by this, Only the Spectra plugin buttons.

When a button background color is set in the site editor the Spectra button blocks will not display a different background color. They will only display the #6366F1 defined in the theme.json, even when a different color is specified for the block in the editor. They appear correctly in the editor, but still display the default on the displayed page. The only exception is if there happens to be a Gutenberg core button on the page also. In only this case will the Spectra button display correctly. If we remove the Gutenberg button then the issue will return.

I have tried to document as much as possible. Please keep up the amazing work and thank you for this incredible product!
