Thank you for the reply.
I have ended up using custom code as suggested. Here's the code if it benefits anyone
sl_reliable_tickvalue = sl_tickvalue * sl_point / sl_ticksize;
if ((Digits == 3) || (Digits == 5)) {sl_reliable_tickvalue = sl_reliable_tickvalue * 10;}
sl_value = (sl_capital_to_risk * stop_loss_percentage /100) / (loop_size * sl_reliable_tickvalue );
In a 'Modify Stops' block, if I set:
New Stop Loss mode = % of the price
New Take Profit mode = No changes
The code will update the take profit anyway, even though I chose "No Change".
I've had a look at the code and found the issue:

And then updated the only OrderSend call as follows:
Code has now been accepted, and my EA is live in the mql5 market
