FL Studio mutes/cuts out my VSTs

Not sure where to post this  (on & off the site as I finish my degree in Illustration/Visual Communication Design this year) but I was wondering if anyone knew how to export FL Studio to .mp3 without it muting/cutting out the VSTs. I constantly have the issue of adding all the instruments that I would like, sounds normal, then after exporting to .mp3, I test the .mp3 version and find it muted/cut out some (of not most) of the VSTs in the final exported piece. It sounds normal in FL Studio (sometimes it still cuts out when playing back the piece in FL Studio - but the issue is guaranteed on export). This is likely a simple fix, but I'm not sure how to solve this issue. I don't create elaborate pieces (as I am self taught and still learning the process), but I'm wondering if there is any way I can salvage the music piece I have created at this point...  It is only 1-2min long... and I would like to continue building on it.  

If you would like to know the VSTs that give me the most issues they are Symphonic Orchestra and Kontakt player. I am using FL Studio 10 (extended memory). Also, If I understand correctly, FL Studio only allows around 4 RAM of room for me to create a music piece - if that is even a factor in the related issue. Let me know if I can provide more info. Like I said, I'm not sure if this fits in this forum, but since I use the VSTs, i figured perhaps someone might be able to help... 

Thanks!

Just turn on Notify about rendering mode option on your VST layer 🙂

 

Ah! it works!

0.0 seriously.... it was that easy.... There are so many projects where this has happened and I've just moved on to the next idea since I didn't think I could build on them anymore and I couldn't share it to the public since it wasn't decently created yet.  I'm SUPER excited to continue working on some of those projects now that I realize this is all that was needing to be done. Thank you SO very much for your help. So simple... I can't believe I didn't know this.
