Weird bug confirmed whether using inline rolls or normal rolls. Create a macro that does " /roll 1d20 + 5 &{tracker:+} " Open the turn order tracker Select a token on the Object layer Add it to the turn order tracker either manually or clicking the turn macro. Repeat steps 3 and 4 with different tokens so you have at least 2 with different initiative values. Click any token, on the object layer, then click your turn macro a couple of times. The token's initiative value updates correctly. Move any token in the turn order. Click any token, on the object layer, then click your turn macro a couple of times. BUG - The result from the turn order macro is now being appended to the selected token's initiative value instead of incrementing it. Repeating the above steps except replacing the "+" with a "-" causes expected, and correct, results.
