Accordian outputs as HTML when placed inside another shortcode

Hello,

I have a custom tab shortcode similar to your other plugin. When I place the Accordian shortcodes within my tab shortcodes, they our printed to the browser as html.

Example code:

[tabgroup][tab title="Technology Skills"]
[accordion tag=h3][accordion-item title="+ Java Developer"]Details to be added soon[/accordion-item][accordion-item title="+ SAP ABAP Programmer"]Details to be added soon[/accordion-item][/accordion]

[/tab][tab title="Scientific & Clinical"]
[accordion tag=h3][accordion-item title="+ Clinical Data Analyst"]Details to be added soon[/accordion-item][accordion-item title="+ Scientific Research Associate"]Details to be added soon[/accordion-item][/accordion]

[/tab][tab title="Miscellaneous "]

[/tab][/tabgroup]
