LFO Mode sync doesn't recognize pattern loop in FL Studio


I made Text to Wavetable Patch and one LFO controls the tempo of the words, the LFO Mode is “sync”. I want to play that pattern several times in a loop, but it only plays the first pattern correct. If the pattern starts the second time, it doesn’t start the LFO from the beginning, but plays the whole LFO curve to the end and only then it starts from the beginning again. So, I can’t play that patch in a song, because the LFO is not synced to the pattern. I also tried the other modes, but only the sync Mode plays the whole text.

Thank you for help!
