We need some more information. Where is this plant growing? What sort of temps? Does it get plenty of sunlight? Is it just the lower leaves that are falling? This is generally not a cause for worry as all plants, tropical or otherwise, lose leaves from time to time, especially in winter. If your conditions are cool, give this plant v little (if any ) water till the weather warms up.

It is growing in a pot and it is place in the living room in a corner by the main window (south) It is very sunny but the plant doesnt get direct light. Temps are between 17C-21C. Plant is not growing at the moment it has one leave that is comming out but it is been like that since I bought it months ago ( like if the growing process had stopped ). Maybe it is normal as you mention but it is a bit worring that all of a sudden 5 or 6 big leaves are on the floor in a matter of days. But in the ones that are still ok there is no sign of color change.
