using tabs along with simple lightbox plugin

Hello,

I am using wordpress 4.9.4 with Tabs 2.0.2 licensed. I am trying to include a photo gallery inside a tab and to do so I am using a plugin published at https://co.wordpress.org/plugins/simple-lightbox/

The gallery shows fine but unfortunately the following tabs will permanently show below the rest of the tabs.

If the lightbox gallery is excluded from the content, the tabs will work fine. The developer of the lightbox plugin publishes some documentation at https://github.com/archetyped/simple-lightbox/wiki/Shortcodes. I was trying to use [slb_exclude] on the messed up tabs without success.

Any advice is highly appreciated.

Thanks in advance for your help.
