You need to subdivide the plates further. Currently, the length of the longest side to the shortest side of each element is 5/0.17 = approx. 29.5

A value greater than 8 triggers the warning message.

Your editor file is not having node no.50 51 52 and 53. Plate no 4 in the model is attached to some other nodes. Whether the warning that you spoke to pertains to this model or some other model.

It appears to me that all the 4 nodes are not in one plane. That may be checked with the joint coordinate. one coordinate (x or y or z) for all the 4 points has to be the same. Pl check.
