Because this does not happen in Strategy Tester, is there a chance that there is other EA working in background that you forgot about and probably contains blocks that modify SL or TP?
Especially in this project, the only block capable of modifying SL or TP is that Trailing stop one. But it is set to move SL only and the opposite stop (TP in this case) is set to No change. If the problem happened in Strategy Tester, then maybe the problem would be somewhere in this block.
By the way "For each Trade" is not needed there. You can place "Pass" instead or even connect block 16 to the yellow output of 1
