Trigger getting stuck after running for a day or 2

Hi,

I am trying to run slightly modified version of the Little Acorns system with the Fibonacci sequence staking plan in horse racing. 

The base trigger runs fine but I need to modify it to ensure that it does not place a second bet before the previous matched bet is settled.

I tried doing using the below method.

When I run this trigger in test mode it runs fine and behaves as it should. I tested it over a 2 week period. The problem is that in real money mode it runs fine for a day or 2 and then gets stuck. 

I have attached a screenshot of the trigger logs of the condition in the laying trigger that it gets stuck at.

I have also attached the base trigger as well as the modified trigger.

Any help will be greatly appreciated.

Thank you.
