Nagios Graph problems with "____" in the end of String

[micneon]

I get in Nagios Graph errors at a new Supermicro Mainboard with ESXI 6.5
The error is:
No data available: host=xxxx service=ESXI Check db=P4Tem_4_Other_4_HDD_
No data available: host=xxxx service=ESXI Check db=P4Tem_4_Other_4_AOC_SAS_

in the shell this infos i get:

P4Tem_3_Other_4_AOC_SAS_Temp___=49;100;105 P4Tem_4_Other_4_HDD_Temp_______=32;50;55

how can i fix it?

is it okay to fix it with that fix ?

remove Line 774
<perf_el = elementName.replace(' ','_')

new 2 new lines

elementNameClean = elementName.strip ()
perf_el = elementNameClean.replace(' ','_')
