Slider/Tab Combo Help

Hello, I’m seeking assistance with a pricing tab slider I’m developing for work. The tabs are categorized as ‘Yearly’ and ‘Monthly’. I aim to have both tabs consistently display four tiers at a time as they slide, with a total of eight tiers. Currently, they’re inconsistent, sometimes showing four tiers and sometimes not. Can anyone advise on how to achieve this or suggest a potential solution? Thank you.
