error message : called on invalid objects

Hello,

i'm using Max7 recently and decided to work on an instrument i made on 6 in 7. So far everything went right, the patch runs perfectly in 7.
Unfortunately, thing began to bug once i decided to save my patch as an app.
Each time i open the app : i got theses two messages
method sizeinsamps called on invalid objects
method fillcalled on invalid objects

i read some threads on the forum about call of invalid objects and deleted all MFL objects a had in the patch.
But nothing changed.
The two messages are still there, and on opening if i click on two toggle button of the patch linked each one to a freqshit object i got an awfull audio overload. CPU is on 1%.

I will apppreciate some help to understand what is happening and how i could fix this.
Thank you very much
