Not sure I understand all of your questions but I will try my best to answer:
Q. Why is it starting on Measure 2 and not 1?
A. Because I added a count-in of 4 closed high-hat hits in the first measure. The first note is set to a velocity of 1 so as to not sound.
Q. When I try to change it on digital audio workstation (DAW) i lost the tempo change.
A. I don’t know what you changed but if you removed the count-in and then cut the MIDI region in Logic Pro X, that might explain why you lost the tempo change. I’ve exported the drums and bass MIDI regions from LPX.

Q. How can i make tempo change on beatbuddy?
A. You can’t easily make tempo changes in the BeatBuddy within a one-press song.
Within the attached MIDI file (which I exported from LPX after I edited the source file), I changed the BPM from 82 to 114 starting at measure 117 through the end of the MIDI region. You can change the tempo but you have to do so in the MIDI source file I provided for the song in post 5, above. To do that, you can try to follow the tutorial provided by Phil_Flood on this forum. Here’s the search results and you will use the text from parts 1 and 2 to guide you through the process. NOTE: Before the server crashed, the tutorials had attached images but they were lost so now it’s just the text that remains. You might also want to read the other threads in that link as well as they provide some useful information.
