2kxl sync issue with Pro Tools

Hey!
I`m having a problem on a new PT session I`m working on. After going into song mode on the MPC, then converting the song into a sequence (160 bars long), it will not sync anymore. I`m using MTC (can`t use clock due to some other issues).
When I press play on Pro Tools, the MPC jumps to the last bar and doesn`t play. The original sequences that are 8 bars long sync without any problem. Also if I open a different Pro tools session, the 160 bars long sequence will play perfectly along.
I reckon it`s a problem with PT, but maybe someone here in the forum knows what it is?
Thanks!

Check...

You can set the start time of the sequence or song when synchronizing with MTC.

Move the cursor to the Now: field in the Main or Song Screen and press OPEN WINDOW to display the following window.

......................................................................................................
Time Display
Display style: BAR,BEAT,CLOCK
Start time: 00h00m00s00f00
Frame rate: 25
......................................................................................................

Start time: The playback starts when the time code set here is received.
Frame rate: Sets the frame rate of the time code

...against the Pro Tools Session Start time and Timecode Rate in the Session Setup window.
