Subtitles not all displayed on screen

[robrom]

BSPlayer Free v1.32 build 199, Android 7
Some lines of dialogue are not displayed as subtitles on some movies I play in BS Player on Android.
I want to use BS Player on my android devices but Unfortunately I cannot watch movies without subtitles.
On my windows lap top I have been using Pot Player and when I first used Pot Player it also had this issue.
When I contacted them they where able to very quickly fix the issue and all subtitles now always display using Pot Player.
Please can somebody help to fix this issue in BS Player as I really like the app and would want to use the pro version on android if this issue can be fixed.
I can supply a link to a very small movie file that this issue can be seen in when played in BS Player.
Very new to forums so not sure if I can supply a link or not.
Any help Appreciated.
Thanks
