Lot of bugs/incompatibilities

Hello,

when I started using Woocommerce product tabs (from SkyVerge), the Brand tab on the product page disappeared, when I tried to add it through custom product tab by displaying the brand with shortcode, it is not working (there is no text, only brand name/image). check for example here: https://goldencloud.sk/oblako-phunnel-m-glaze-zltocerveny-mramor

When I tried to check the Brand page, there is nothing displayed, although I tried to troubleshoot it with default theme and all other plugins (besides of woocommerce) disabled.

I also tried to add brands there with A-Z list and I think its not displaying correctly at all … look: https://goldencloud.sk/znacky

The perfect brands plugin is not so perfect 🙁 Can you please help me fixing it?

I also asked you for improvement few tickets below, if you can change the tab name from “Brand” to actual name of the brand and didnt get any response, but this is not so critical as the bugs above.

Thank You for helping me in forward
