Error Saving Database caused by wires created during ECO

It seems like old nets are kept in the database even if they are not in the new eco netlist. For example, I had a change that made this code:

   DTC23 \otpData_o_reg[spare2][0]  (.Q(\otpData_o[spare2] [0]),

               .D(n_18),

               .CLRZ(p4),

               .CLK(clkTrim17Lo));

   DTC23 \otpData_o_reg[spare2][1]  (.Q(\otpData_o[spare2] [1]),

               .D(n_17),

               .CLRZ(p4),

               .CLK(clkTrim17Lo));

   DTC23 \otpData_o_reg[spare2][2]  (.Q(\otpData_o[spare2] [2]),

               .D(n_15),

               .CLRZ(p4),

               .CLK(clkTrim17Lo));

   DTC23 \otpData_o_reg[spare2][3]  (.Q(\otpData_o[spare2] [3]),

               .D(n_16),

               .CLRZ(FE_OFN235_porZ),

               .CLK(clkTrim17Lo));

Change to this:

   DTC23 \otpData_o_reg[spare2][0]  (.Q(NVM_TRACKER_SEL),

               .D(n_18),

               .CLRZ(p4),

               .CLK(clkTrim17Lo));

   DTC23 \otpData_o_reg[spare2][1]  (.Q(NVM_BOOST_DIS),

               .D(n_17),

               .CLRZ(p4),

               .CLK(clkTrim17Lo));

   DTC23 \otpData_o_reg[spare2][2]  (.Q(NVM_SYS_ALT_SEL),

               .D(n_15),

               .CLRZ(p4),

               .CLK(clkTrim17Lo));

   DTC23 \otpData_o_reg[spare2][3]  (.Q(otpData_spare2_3),

               .D(n_16),

               .CLRZ(FE_OFN235_porZ),

               .CLK(clkTrim17Lo));

So, I am only changing the output net to a new name. When I do this, Encounter takes the old names (i.e. \otpData_o[spare2] [0]) and defines internal wires for them like this:

   wire \SPARE[19] ;

   wire \SPARE[20] ;

   wire \SPARE[21] ;

   wire \\otpData_o[spare2] [0] ;

   wire \\otpData_o[spare2] [1] ;

   wire \\otpData_o[spare2] [2] ;

   wire \\otpData_o[spare2] [3] ;

The “\\” is keeping the database from saving. I get this error when trying to save:

**ERROR: (ENCOAX-156):  OA Exception : Input name (or member): \\otpData_o[spare2] [0]  has improper bus syntax..

**ERROR: (ENCOAX-426):  Error in creating EMH hierarchy.

TIMER: oaOut total process: 0h 0m  0.05s cpu {0h 0m 0s elapsed} Memory = 0.0

**ERROR: (ENCIMEX-7323):        Could not save design into OA database.

Does anyone know a way to tell Encounter not to name it with \\ or how to remove the old physical wires from the database??  This is a postMask ECO, so I cannot re-synthesize. 

Thanks!
