SEND shifting numbers into their special characters when preceded by uppercase

[redcantelope]

I'm having an issue with the SEND command when sending a variable containing both uppercase letters and numbers . SOMETIMES, but not always, it appears to be unable to release the "SHIFT" key in time when a number follows an upper case letter. I'm copying and pasting in/out of text fields in a Filemaker Pro 11 application.

[*] I've confirmed this is an issue with the SEND command and not the variable string by using MSGBOX to display the variable immediately after the SEND command. The MSGBOX shows the variable is correct.
[*] I've confirmed it's shifting the number key and not a static substitution by swapping out the number being sent and the placement of upper case letters

Example1:
Variable = P1BEO10
SEND will sometimes send "P!BEO10"
"1" was replaced with [SHIFT+1], AKA "!"

Example2:
Variable = P2BEO10
SEND will sometimes send "P@BEO10"
"2" was replaced with [SHIFT+2], AKA "@"
Shows it doesn't matter what number is following an uppercase letter

Example3:
Variable = P1beO10
SEND will sometimes send "P!beO10"
"1" was replaced with [SHIFT+1], AKA "!"
Shows it doesn't matter if the number is followed by an uppercase letter

Example4:
Variable = PbeO10
SEND will sometimes send "PbeO!0"
"1" was replaced with [SHIFT+1], AKA "!"
Shows it doesn't matter where the number is in the string, but appears to only be the first number in a string following an uppercase letter

Example5:
Variable = p1beo10
SEND sends the string correctly every time (no preceding uppercase letter)
Shows the number has to be preceded by an uppercase letter

Example6:
Sending the prefix separately from the final two digits in two separate send commands also results in the problem
SEND variable containing "P1BEO"
SEND variable containing "10"
result: P1BEO!0
