Ties not showing on android tablet

I have an issuie which is driving me crazy.
When I am looking at score from my tablet the tie (curved lines) between tied notes for example is not showing.
Im not writing the score myself, just looking at and playing and I used to be able to see the ties.
I have attached a couple of screenshots to show whats happening.
You can see a screenshot from my mobile which shows the ties and another from my tablet with the missing ties. The tablet and mobile are both android.
I have tried clearing app data and even uninstalling and reinstalling but issue still remains the same.
