The help file says that FontCreator 10 supports all types of substitutions.

If a feature does not work in the Preview Toolbar, open a font Test Window, select the test font in Word or whatever application you're using, and test the feature there.

I don't have an Urdu font installed. OpenType features do not work in the font test window. You have to test it in Word (or whatever) after installing the font, or using the temporary file name generated by the Font Test window.

There are only 8 lookup types defined, and lookup type 8 is the Reverse chaining context single.

Previous versions had limited support, but the most recent version of FontCreator fully supports all OpenType layout features.

We've just noticed a bug which might cause issues when opening fonts which contain GSUB lookup type 8. We will release an update within a few weeks which should solve this issue. If you can't wait, let us know as we will send the new release on request to existing customers.

i opened onther font name "Pak Nastaliq" in font creator 10.1 which also have type 8 tabels, font creator was just read the lookups, the lookups are not included in the ContextualAlternates feature. i have attach the font plz check it.
Urdu Typesetting font type 8 tables are also just read, The calt feature have not included. I think this is a bug.

We've found another issue that affected your font. It should show these lookups:

I've exported two fonts and installed them. Here is some text in a Word document which comes from news about tennis:

وانسحبت التشيكية، كارولينا بليسكوفا، المصنفة رابعة، التي فازت ببطولة برزبين أمس السبت من بطولة سيدني بسبب إصابة في الفخذ. وستصعد بليسكوفا إلى المركز الخامس في قائمة التصنيف الدولية الجديدة، التي ستصدر غدا الاثنين، بعد الفوز في برزبين.

I didn't see any difference between original and exported versions of these fonts, so it now seems to work just fine.

Thank you for confirming the issue is fixed!

And the Font Test dialog also looks great to me:
