NMDS does not work with specific data set - r

Question

Im currently trying to run an NMDS with two subsets of a data set: metalimnion and hypolimnion. If i seperately subset the metalimnion data and run the NMDS it works fine but if i include the hypolimnion data i get errors saying that the data is insufficient:
for(i in 1:10){
tmp<-metaMDS(dSS.scree, k=i, autotransform=FALSE)
dimension[i,1]<-i
dimension[i,2]<-tmp$stress}
Warning messages:
1: In metaMDS(dSS.scree, k = i, autotransform = FALSE) :
stress is (nearly) zero: you may have insufficient data
Here's a portion of the data since its quite large:

"POSIXt"), tzone = "UTC")), row.names = 20:25, class = "data.frame")
Both datas combined is larger than each seperately yet I get this error. Any idea as to why?
