Next / Previous links are reversed

[humantex]

I can successfully create portfolios and projects, and have changed the ordering using any/all setups offered - but - the previous/next links shown on individual project pages aren't shown in the proper context as left-side = previous, and right-side = next. Opening the 1st/left-most project listed in the portfolio, shows the next/2nd project as a 'Previous' link underneath it, at screen-left, with no right-hand 'Next' link at all.

It's not a CSS issue (using incorrect 'float' positions), and it doesn't seem to be caused by the template/view code - so I doubt I can do a basic override just to swap their positions. I'd need to insert both the missing ':before/:after' pseudo-classes and rework all the associated CSS to force it to render somewhere close to the expected result.

Two different sites are using the same extension and both are presenting their portfolio/project pages with the links reversed....

Site 2 (Dev): https://enew.electrodedressers.com/edi-products-and-services

The extension is the last version posted, and was installed to both sites via the Marketplace.
