Joined Repeatable list/form calc problems

I've been running a particular Fabrik form in J3 for some years without issue, it's a simple sale entry with the sale detail - customer, order date etc in the main List/Form (t_sales) and the items ordered in a joined repeatable List (t_sale_items).
The first screen print illustrates how it looks with some Calc fields settin the net price/unit and line totals

I tried updating this to J4.3.1 F4G3 and had so many problems I decided to start from scratch but have run into a similar problem in the new build.
Below you can see that the new build calculates fine in the first line of the repeat group but then fails - in fact it just takes the value from line 1 irrespective of the changed detail in subsequent lines. Further, as can be seen, it switches the first Yes/No field without input from the user. I'm seeing no warning or errors in the Consol or Network, etc. Any ideas please?

 

Sorry had problem with images ...

 

Please bear with me, I should have mentioned that the calc fields all carry the same _0 suffix, whereas the other fields run _0, _1, _2 etc as they should.

 

That's great thank you, the calc is working again. However, I still have the first Yes/No field switching from default Yes to No on load, back to correct Yes in second repeat row and to No again for subsequent rows. Tried to work around with radio buttons, but that's irregular in a similar way too.

 

Again thank you. Is there a fix for the radio buttons too which which repeat ok for the first repeat row but then ignore defaults in the third and subsequent repeats?
