It may not be your ACS routines.
I can reproduce this behavior on a "test" LPAR when allocating a PDSE
in ISPF 3.2 with RECFM=U. I get the warning message to either DELETE or KEEP
the dataset. If I keep it, I can't copy Load modules or program objects into
then newly created D/S.
If I allocate the PDSE with either a Fixed or Variable RECFM, then
BLKSIZE of 0 (or BLANK) is accepted. In the cases of RECFM = FB or VB, SDB
produces an optimum block size for my device type.

"Allocation" is dismayingly ambiguous. But I assume you mean allocation as in
DISP=NEW ratner than allocation as in DISP=OLD.
Data Set Utility tells me:
Data Set Name . : User.LOADE
Specified data set has zero block size.
The data set allocated contains inconsistent attributes as indicated by the
message displayed above. Prior to allocating a managed data set, ISPF cannot
always determine if the attributes are inconsistent. The data class used when
allocating the data set may contain inconsistent attributes, or the attributes
you specified on the allocation panel may conflict with those defined in the
data class. This panel gives you the opportunity to delete this data set. If
you keep the data set, other ISPF functions, such as edit, move, or copy, may
not be able to use the data set.
But I keep it. Then Data Set List says:
