Cannot set InBagFraction for treebagger regression

I am trying to train a random forest that performs a regression using the treebagger class. As I have a considerably high amount of data, I would like to set a InBagFraction<1 . My code is the following.

tree=TreeBagger(numTrees,X,Y,'method','regression','NumPredictorstoSample',numPTS,...
                'oobvarimp', 'on', 'minleaf', minLS,'InBagFraction',0.1);

The function crashes with the following error:

Subscripted assignment dimension mismatch.

Error in TreeBagger/growTrees (line 797) bagger.InBagIndices(:,NTreesBefore+1:NTreesBefore+NumTrees) = slicedInBagIndices;

Error in TreeBagger (line 619) bagger = growTrees(bagger,NumTrees,'Options', parallelOptions, 'nprint', nprint);

Is it a bug ora am I doing something wrong?
