Added Products not shown in Grouped Product.

Before installation of this plugin, everything is shown perfectly.

Like

Grouped Product Title
Qnty Added Product Title Price
Q1 AddedProduct1 1$
Q2 AddedProduct2 2$
Q3 AddedProduct3 3$
Q4 AddedProduct4 4$

and so on.

But when I installed this plugin, its showing like below:

Grouped Product Title
Qnty Added Product Title Price
Q1 GroupedProduct 1$
Q2 GroupedProduct 2$
Q3 GroupedProduct 3$
Q4 GroupedProduct 4$
and so on.

So its showing groupproducttiel instead of added product title.

So many times tried to get support/chat on their website. This is worst experience had with this plugin.
